Steam crashes with an illegal instruction on pre-SSE3 processors #5164

Steam client falls after authorization. Output from the command line:

And not working with package from Ubuntu 17.10 (1.0.0.54+repack-2ubuntu5). Also not working with same problem on Debain 8 32-bit with last updates (worked earlier fine). Steam client version 1.0.0.49-1.

I'm tried install same OS (Ubuntu Mate 16.04.03 32-bit) with same version of Steam client (1.0.0.48-1ubuntu4) on VirtualBox on other hardware. Working fine.

Hello @zevilz, please add a gist of your ~/.steam/error.log and the corresponding minidump in /tmp/dumps. I suspect steam is trying to run an SSE3 instruction in SDL2, but the processor does not support SSE3.

Thanks @zevilz. This is as I suspected, an SSE3 in the steam runtime provided SDL2. You could try to build libSDL2-2.0.5 (or newer) from source or add a symlink to a system variant of the library in ~/.steam/ubuntu12_32/steam-runtime/pinned_libs_32, but there may be unexpected side effects.

I'm install libSDL2-2.0.5 from Zesty (ubuntu 17.04) repository and add symlink to libSDL2-2.0.so.0 in ~/.steam/ubuntu12_32/steam-runtime/pinned_libs_32. Same problem without errors. Then i'm replace libSDL2-2.0.so.0 in ~/.steam/ubuntu12_32/. But client check his libraries after start steam and restore original files

BVerifyInstalledFiles: ubuntu12_32/libSDL2-2.0.so.0 is 1260452 bytes, expected 1013365

Then i'm replace original file after libraries check. Same problem again.

I see it's been some time since this issue was first noticed... Are there any currently known workarounds?

lisikh commented 5 years ago

Here is my workaround.
You need libSDL 2.0.9 as it contains all necessary calls. For ubuntu 18.04 there is a binary package. For ubuntu 16.04 I compiled source package with gcc 9. The hint is to get smaller library than original steam-shipped. Next, append your library with zeroes to equal original size as steam client only checks file size: dd if=/dev/zero of=libSDL2-2.0_new.so.0 count=1 bs=$(( $original_size - $your_size )) oflag=append conv=notrunc Replace your library to ~/.steam/ubuntu12_32/ Enjoy steam on pre-sse3 processors :)
