LLVM ERROR: Function Import: link error: linking module flags 'ProfileSummary' #54416

Hi.

We are getting this crash when using PGO in Unreal Engine 4, Linux. The crash seems intermittent. It isnt clear exactly what triggers it. We generate PGO data every night and use it in subsequent builds.

Any workaround would be appreciated.

Version:

LLD 11.0.1 (https://github.com/llvm/llvm-project 43ff75f2c3feef64f9d73328230d34dac8832a91) (compatible with GNU linkers)

Callstack:

Same problem in 13.0.1. I realize you dont have the debug symbols, but any help would be appreciated.
