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
problem defied my expectations.
