Why gprof gives empty log file on Windows 10?

8

It should be a bug. A year ago, I found that gfortran and gprof of MSYS2 on Windows generated empty reports. This problem still exists (currently gfortran 11.3 still has this problem), while gfortran on WSL2 has no problem.

empty log 
>> gprof -b ./main.exe gmon.out
