Another crash while using checkedC

[Arslan8]

Hi,
I encountered another crash while using checkedC. The crash comes after I try to compile bc to native code. I've enabled thin LTO as well. Here's the backtrace:

PLEASE submit a bug report to https://github.com/Microsoft/checkedc-clang/issues and include the crash backtrace.

Thank you for reporting this issue. It would be great if you could attach a (reduced) test case, and the compilation command line!

[Arslan8]

Hi @sulekhark! I'll try to make a reduced test case but the project i was running had more than 100 files all merged into one temporary .bc file due to LTO so it will take some time on my end..will post the test case or bc file here soon..
