[PATCH] D112337: [DebugInfo] Only create concrete DIEs of concrete functions

Wed Nov 10 13:42:11 PST 2021

jgorbe added a comment.

I rebuilt clang at this commit with `-DLLVM_USE_SANITIZER=Address` and it reports a problem nearby. I don't know if this patch is the actual root cause for the crash or if it's triggering an existing bug. Here's the full report in case it can help you debug the issue further:
