backtrace of the crash
While testing <a href="https://reviews.llvm.org/D70631">https://reviews.llvm.org/D70631</a> with the libc++ buildkite CI this
build results in an crash
<a href="https://buildkite.com/llvm-project/libcxx-ci/builds/6587#d7ec64f2-e31a-4d73-8d6c-e118e63a0cc1">https://buildkite.com/llvm-project/libcxx-ci/builds/6587#d7ec64f2-e31a-4d73-8d6c-e118e63a0cc1</a>
The CI job builds clang and uses that Clang to build the patch.
<a href="https://github.com/llvm/llvm-project/blob/main/libcxx/utils/ci/run-buildbot#L470">https://github.com/llvm/llvm-project/blob/main/libcxx/utils/ci/run-buildbot#L470</a>
Two work-arounds are
- Remove -DLLVM_ENABLE_ASSERTIONS=ON
- Change the build type to Release
Attached the backtrace and reduced reproducer.</pre>
