When I running the a test program with LLDB (with this PR), LLDB crashes. I don't have a reduced test case yet, will probably working on getting one when I have time: ``` Please include the directory content when filing a bug report PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
