It appears to be miscompiled on hppa and causes the FTBFS. 18.2.8-2 was built with gcc-7. The new 18.3.0-1 on experimental in now built with gcc-8. I did a test build of mesa with gcc-8: https://buildd.debian.org/status/fetch.php?pkg=mesa&arch=hppa&ver=18.2.8-2%2Bb1&stamp=1547428024&raw=0 However, it has same code issue
At this point, I think the problem is with gcc. Either the instruction after the movb should have been nullified, or it shouldn't have been put in the delay slot of the movb. I need a build outside buildd to investigation further. I haven't looked at the code for dri2_query_wayland_buffer_wl (i.e., what happens when wayland_drm_buffer_get() returns NULL).
