[solved, I guess] Steam segfaults with the latest mesa update

With the latest update to lib32-mesa, steam will not start at all and segfaults instantly. So far the only workaround I've found is downgrading lib32-mesa and reinstalling the lib32-vendor-dri package relevant to your GPU, lib32-intel-dri in my case. It works but it's not much of a solution. Has anyone got a better idea?

Re: [solved, I guess] Steam segfaults with the latest mesa update

Do you typically run Steam with "STEAM_RUNTIME=1" or  "STEAM_RUNTIME=0"?

For me, I cannot run without runtime enabled, perhaps that is also related to the lib32-mesa update.
Edit:
I ran gdb with steam's native runtime, and the few errors it caught may be able to bring to light why this issue is occurring.
Seems like after it receives SIGSEGV from /usr/lib32/libc.so.6 is when it terminates.

Program received signal SIGTRAP, Trace/breakpoint trap.
0xf4ccfd87 in AssertMsgImplementation () from /home/bigstiffy/.local/share/Steam/ubuntu12_32/libtier0_s.so

Program received signal SIGSEGV, Segmentation fault.
0xf7bfae86 in __strlen_sse2_bsf () from /usr/lib32/libc.so.6

I have since tried removing the file libc.so.6 links to, purging lib32-glibc and reinstalling it, but no change.

Re: [solved, I guess] Steam segfaults with the latest mesa update

I usually run without any STEAM_RUNTIME setting, if I set it to 0 it complains about some missing libraries.

I was going to run it through gdb to check if I get the same result that you do but… I updated to latest mesa again and now Steam works. I have no idea what fixed it, oh well ¯\_(ツ)_/¯

Glad the issue resolved itself. I'll move my problem to a new thread.
