v1.1.0: Illegal instruction (core dumped)

[peterk87]

Describe the bug

Illegal instruction (core dumped) errors when trying to view any alignments with the same args ($ gw -b input.bam refs.fasta -r "$ACCESSION") as used with gw v1.0.0.

To Reproduce

Built v1.1.0 from source on Arch Linux (g++ (GCC) 14.2.1 20240910):

git clone https://github.com/kcleal/gw 
cd gw
git checkout v1.1.0
bash deps/build_skia.sh
make -j4

Minimal reproduction of issue:

$ ./gw

Illegal instruction (core dumped)

Expected behavior

No core dump.

System (please complete the following information):

• GW version: 1.1.0
• OS: Arch Linux x86_64 (Linux 6.10.9-arch1-2)

Additional context

Window Manager: KWin (X11)
Desktop Environment: KDE
GPU: NVIDIA Corporation TU104GLM [Quadro RTX 5000 Mobile / Max-Q]
Nvidia driver version: 560.35.03

Fortunately, gw installed from Conda works now, so that's what I've been using.

Thanks for making a simple, fast and easy to use alignment viewer!

Hi @peterk87,
Thanks for reporting, I have not tested on Arch, or many other Linux flavours other than Ubuntu and centos. Just curious, did you try one of the prebuilt skia binaries using make prep instead of building skia? Also wondering if you get the issue with a local reference genome.

[peterk87]

Hi @kcleal, thanks for following up.

I tried compiling with the prebuilt skia binaries following the updated instructions in the readme, but I still get the same issue with v1.1.0 and master at e2ae602

conda create -y -n gw_env -c conda-forge glfw htslib
conda activate gw_env
git clone https://github.com/kcleal/gw.git
cd gw && make prep
CONDA_PREFIX=$(conda info --base) LDLIBS+="-lcrypto -lssl" make -j4

This is the backtrace from the core dump:

Core was generated by `./gw'.

Let me know if you need any more info!

[kcleal]

Hmm thanks for sharing. It looks like the crash is happening when skia is trying to use the Menlo typeface. You might be able to fix this by changing the font name in the the config file usually located at ~/.config/.gw.ini - try changing to Default or a common font like arial🤞

[peterk87]

I tried changing the ~/.config/.gw.ini to different fonts installed on my system and even tried installing the Menlo TTF from https://github.com/maltalef101/menlo-regular-font and copying over whatever fonts were present in the gw Conda env to ~/.local/share/fonts but unfortunately I still encounter the same issue.

gw installed with Conda still works great though!

[kcleal]

Thanks for trying!

[gtbil]

I am also getting the same error. I'm on CentOS Stream 9. Happy to try debugging further.

[kcleal]

Hi @gtbil,
Did you manage to get it working via conda? How did you try and install GW? Thanks!

[gtbil]

Yes, it did work with Conda. I tried to install GW using the instructions provided here under Build from source. The pre-built skia binary did not work so I had to build it using the provided instructions, with build_skia.sh.

[kcleal]

Ok thanks, Grant.

Did the pre-built skia binary and the built-from-scratch skia give the same core dumped problem?

It's a tricky one to understand. It looks like the issue arises from skia doing something funky when trying to create a font. This is the gw code causing the issue in gw/src/themes.cpp:

const char * font_c = fontStr.c_str();
face = SkTypeface::MakeFromName(font_c, SkFontStyle::Normal());

If the font name is set to 'Default' in the .gw.ini, that should avoid this block of code entirely. Alternatively, if you add a print statement to see if fontStr is a valid typeface, that might be useful to know. Or you can replace the MakeFromName function call with:

face = SkTypeface::MakeDefault();

If there is still a core dump, then the issue is not from the gw code and could be skia or fontconfig. It's interesting that the conda binary still works as that uses the pre-built skia. This makes me think it might be the fontconfig library on your system....

[gtbil]

I couldn't even get gw to compile with the pre-built skia binary.

So it actually looks like my stacktrace is different: My font name is set to Default.

For what it's worth here's the fontconfig package on my machine: fontconfig-2.14.0-2.el9.x86_64 (and fontconfig-devel-2.14.0-2.el9.x86_64):

Here's the output from coredumpctl gdb -1:

[kcleal]

Ah ok, that's quite helpful. It looks like the issue arises from freetype which itself is compiled as a static lib during skia compilation. I believe you can switch off freetype compilation when building skia. You can try adding this to the gn args in build_skia.sh:

skia_use_system_freetype=true

Or possibly just:

skia_use_system_fontconfig=true

I will need to move to a later version of skia, its possible this issue has been resolved in one of the newer releases.

[gtbil]

Cool! I compiled Skia with these instructions (and an additional compiler flag, "-Wno-everything" to suppress an error from a Skia dependency warning during the build):

bin/gn gen out/${REL} --args="is_debug=true \
    skia_use_system_expat=false \
    skia_use_system_freetype2=true \
    skia_use_system_harfbuzz=false \
    skia_use_system_icu=false \
    skia_use_system_libjpeg_turbo=false \

Now getting a different error. Before, the GUI was not appearing, but now it appears and immediately crashes:

Ok I think I understand - this is still related to the first error. The illegal instruction is probably from the wrong SIMD flags being used at compilation. You can check what your CPU supports using lscpu I believe. I'm not sure what needs to be passed as a cxxflag, maybe -march=native. I will have a look tomorrow. Thanks for your input, much appreciated 👍

Awesome, thank you!! Removed all the SIMD-specific flags and replaced them with -march=native. Now a new error.

[kcleal]

Ok maybe try a baseline

-march=x86-64

If that doesn't fix it then I will have to move to a newer skia version I think. It will take a bit of time as the API will be different in the newest version.

[gtbil]

No luck, same error.

[kcleal]

Ok one last try could be:

-march=core2 -mtune=haswell -mssse3

[gtbil]

Still doesn't work unfortunately.
