The requested operation cannot be performed on a file with a user-mapped section open.

Hello I have problem - and I’m always able to reproduce it. If you have single file that is bigger than hello world example (https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Developer/BlueprintProfiler/Private/BlueprintProfiler.cpp <- used this one to reproduce) make sure there are some error like missing symbols etc (i just setup single .cpp file) then try to save it relatively quickly then you get error I mentioned in the title.

I think it’s some timing issue between saving file and opening it by clang to compile.

@niosus Also, worth mentioning this is just not happening very rarely, it happens with all files containing errors, so i’d say this bug is critical as it makes the plugin basically unusable

I had the same issue and reverting back to clang 4.0.1 fixed it. (UPDATE: i actually got the error one more time after downgrade to 4.0.1, but it worked after that, maybe less of an issue with 4.0.1) Thanks for the post and looking into this, hopefully @niosus finds a fix with 5.0.
