Dolphin-emu: Mesa 17 radeon/amdgpu = segfault


Since Manjaro updated Mesa 13.x to 17.x I've been getting segfaults on dolphin-emu. At first I thought my particular video card (AMD R7 250) was the problem, but then I tried a RX 480 and the same issue happens.

I filed a bug upstrem 22 days ago but no response at all - I cannot be the only one experiencing this issue.

Unfortunately I do not know how to use dolphin's integrated debugger, but I always get this error with dmesg:

Code:
Video thread[10469]: segfault at 48 ip 00007f5b9b6dff58 sp 00007f5bb96f6350 error 4 in radeonsi_dri.so[7f5b9b054000+969000]

Yesterday I decided to look at manjaro for the first time. The installer segfaulted all over the place. Not promising.
I have a R9 something-or-other - had to blacklist the amdgpu on the installer boot to even get it installed. Seems to run ok, but I haven't tried video/games.
I'll fire it up again tomorrow and report back.

Please try dolphin-emu-git. When I had a R7 250 and the radeon / xf86-video-ati drivers running with Mesa 13.x it was fine. I experienced segfauts on dolphin-emu only after the Manjaro update to Mesa 17.x and with other OpenGL-based programs/games (Yamagi-Quake II, Xonotic, TORCS, you name it) the amdgpu driver works fine and dandy.

Currently I'm unable to simply try another distro to narrow the options of where the problem may be since I'm working on my master thesis and this is my only PC.
