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 https://github.com/namhyung/uftrace
$ cd uftrace
$ sudo ./misc/install-deps.sh -y
$ CC=clang ./configure
$ make
CC FPIC libmcount/script-luajit.op
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
