tupos wrote: Hello,
I think there might be some problem with this PR. I updated to 19.1.0 today and started to see crashes with this callstack on random files. So far I was not able to create a minimal working repro to let it reproducibly crashing. Strangely enought it does not always crash on the file, from which I obtained the crash. However, maybe you could have an idea what might be wrong. ``` PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. #0 0x00000000005bde8b
