Package: clang-15 Version: 1:15.0.7-4 Severity: normal X-Debbugs-Cc: c...@slerp.xyz, debian...@lists.debian.org
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: [ 90%] Building CXX object testing/CMakeFiles/test_thrust_zip_iterator_reduce_by_key.dir/zip_iterator_reduce_by_key.cu.o cd /root/rocthrust/rocthrust/obj-x86_64-linux-gnu/testing && /usr/bin/hipcc -D__HIP_PLATFORM_AMD__=1 -D__HIP_PLATFORM_HCC__=1 -I/root/rocthrust/rocthrust/obj-x86_64-linux-gnu/thrust/include -I/root/rocthrust/rocthrust/thrust/.. -isystem /root/rocthrust/rocthrust/testing -Wno-deprecated-builtins -g -O2 -ffile-prefix-map=/root/rocthrust/rocthrust=. -Xarch_host -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -Wno-unused-command-line-argument -Wall -Wextra -std=c++14 -O3 -DNDEBUG -x hip --offload-arch=gfx803 --offload-arch=gfx900 --offload-arch=gfx906 --offload-arch=gfx908 --offload-arch=gfx90a --offload-arch=gfx1010 --offload-arch=gfx1011 --offload-arch=gfx1030 -DGTEST_HAS_PTHREAD=1 -std=c++14 -MD -MT testing/CMakeFiles/test_thrust_zip_iterator_reduce_by_key.dir/zip_iterator_reduce_by_key.cu.o -MF CMakeFiles/test_thrust_zip_iterator_reduce_by_key.dir/zip_iterator_reduce_by_key.cu.o.d -o CMakeFiles/test_thrust_zip_iterator_reduce_by_key.dir/zip_iterator_reduce_by_key.cu.o -c /root/rocthrust/rocthrust/testing/zip_iterator_reduce_by_key.cu PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
