CodeQL tcmalloc build failure clang-11 #23891
Description
Title: CodeQL tcmalloc build failure clang-11
Description:
My recent PR ran into a CodeQL build failure for an external tcmalloc package. Looks like it is not related to my changes, but not sure about that. Can someone also help investigate? Thank you!
Other than that, we are using clang-11 to build targets in CodeQL pipeline. Should we upgrade it?
