<pre>I've seen some crashes when building uftrace, which is a C/C++/Rust function
tracing tool.
Here is the sequence to reproduce the bug.
$ git clone <a href="https://github.com/namhyung/uftrace">https://github.com/namhyung/uftrace</a>
$ cd uftrace
$ sudo ./misc/install-deps.sh -y
$ CC=clang ./configure
$ make
CC FPIC libmcount/script-luajit.op
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace, preprocessed source, and associated run script.
