Package: libelf1
Version: 0.163-4
Severity: normal
Tags: upstream
Hi,
when I link my Mesa build against libelf1, some Piglit [0] tests start
throwing SIGSEGVs. Two of those tests are
spec@arb_gpu_shader_fp64@execution@fs-indirect-temp-double-{dst,src}.
When I link Mesa (or more specifically my driver, which is
radeonsi_dri.so) against libelfg0, the tests pass and run normally.
Michel Dänzer of AMD observed the same problem. You can find a full
backtrace and register dump attached ([1]) to fdo#91520 ([2]) where I
reported the bug initially, thinking it was a bug in Mesa's code.
This is a regression. Previous versions of libelf1 worked. Michel Dänzer
says it must have been introduced between 0.159-4.2 and the current
0.163-4 ([3]).
Let me know, if you need something else.
Cheers,
Kai
