AQTime Light Coverage Profiler identifies uncovered lines with only brackets or keywords (C++)

I have some strange Light Coverage result reported by AQTime (8.71.3483.7) It shows thats the lines containing only brackets (from if-else or try-catch blocks) and `if-else` keywords  are uncovered...

    thanks AlexKaras, it was a good hint.

     

    Indeed, I did run Coverage Profiler with none-Release configuration in MSVC.

    Without /O options MSVC would generate unreachable jmp instructions for such `else` or `bracket` lines.

    It is not wrong but just not nice with MSVC for none-optimzed code generation. Example instruction code generation without /O and with /O options

     

    I assume that AQTime profiler just traces if generated instructions are executed or not. That is why I get this strange result.
