Package: clang-15
Version: 1:15.0.7-4
Severity: normal
X-Debbugs-Cc: [email protected], [email protected]
Dear Maintainer,
I'm having trouble reproducing this problem, but I figured I should
report it anyway in case other users had seen similar behaviour.
While compiling the rocthrust test suite, I encountered a segfault in
the compiler. To move forward with my work, I decided to disable
building the test that triggered the segfault, with the intention of
returning to prepare a simple, self-contained example of the problem
later. Unfortunately, when I returned to prepare this bug report, I was
unable to reproduce the crash. I'm unsure of whether I have somehow
failed to reproduce the original conditions that caused the crash, or
if the crash is non-deterministic.
I originally thought this crash was a regression from 15.0.6, but I no
longer have any reason to believe that. It may just have been luck that
I never encountered this crash before.
The only information that I saved from the failure is this log snippet:

I really must apologise for not collecting all the data required to
diagnose this bug. I was expecting to be able to easily reproduce the
crash and capture the necessary data the second time around, but this

I am closing Bug #1034045 (clang-15: Segfault during compilation of
rocthrust/testing/shuffle.cu), because I now believe it to have been
caused by a hardware failure. I haven't pinned down the exact cause, but
I'm seeing occasional crashing in a wide variety of programs. I suspect
there is a core on my CPU that is not stable under heavy load.
Apologies for wasting your time on a wild goose chase.
Sincerely,
Cory Bloor
