Not sure which of the LTO variables are suitable, maybe both. PGO? Is that the correct variable? The blog-text mentioned t...

Trying to run a self host "ninja check-clang" with ASan enabled I hit a /lot/ of errors like this (strangely I hit none of these in check-llvm, only in check-clang): Any ideas? ==10525==ERROR: AddressSanitizer failed to deallocate 0x10800 (67584) bytes at address 0x631000014800 ==10525==AddressSanitizer CHECK failed:
