I've filed a bug report here: https://bugs.llvm.org/show_bug.cgi?id=50706 I'm going to try to figure out which specific object file is causing llvm-ar to crash. I'll report back when I know more.

I'll report back when I know more.Hi Shawn, Just to make sure, these object files are actually LLVM bitcode, right? (Since you're trying to do LTO here.) -Dimitry -------------- next part -------------- A non-text attachment was scrubbed...
