This repository is for a fork of LLVM dedicated to supporting the AVR chip. I think you have found the wrong place to report this. In fact, if you continue reading your pasted message, it tells you where to go:

PLEASE submit a bug report to http://bugs.debian.org/ and include the crash backtrace, preprocessed source, and associated run script.

Thank you

By the way @gopinath-r - this isn't a debian bug, so if this is still an issue in current master (I don't think it is, I remember working on the ctlz stuff in the past few months), the place to report it would be https://bugs.llvm.org/
