This is an upstream bug for Android NDK bug https://github.com/android/ndk/issues/1685.
I am attaching same .zip file from that bug, which has the source code and compilation command:
[Review.zip](https://github.com/llvm/llvm-project/files/8701595/Review.zip)
This bug was originally reported with version 24.0.8215888, for which `clang++ -v` reports:
`Android (8075178, based on r437112b) clang version 14.0.1 (https://android.googlesource.com/toolchain/llvm-project 8671348b81b95fc603505dfc881b45103bee1731)`
I have reproduce the crash with clang built at head (`clang version 15.0.0 ([email protected]:llvm/llvm-project.git 7272a8c23ceb218b3bd6f0dd303c6df2c773cc74)`, built with `cmake -GNinja ../llvm -DLLVM_ENABLE_PROJECTS="clang;compiler-rt;lld;clang-tools-extra;libcxx;libcxxabi" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_INCLUDE_GO_TESTS=OFF -DCMAKE_BUILD_TYPE=RelWithDebInfo`), albeit with a different stack trace:
```
