It seems like this is related to LOG_NO_FILE_LINE_FUNCTION. Defining it in common.h as-is is definitely wrong, this is just a workaround. I can imagine a few correct fixes.

Ways that would make it mandatory:

• Define LOG_NO_FILE_LINE_FUNCTION in log.h
• Make log.h a private header that can only be included directly by common.h
• Remove the code that is used when you don't define LOG_NO_FILE_LINE_FUNCTION

Ways that would make it opt-in, and require fixing the clang-cl implementation in log.h:

• Define LOG_NO_FILE_LINE_FUNCTION at the top of every .cpp source that uses logging
• Define LOG_NO_FILE_LINE_FUNCTION in the build scripts via -D
