Handles leak on new Visual Fortran Compiler 16.0

[Alex_L_4]

For example, simple code:

    program handlesleak
    implicit none
    integer(4)      :: i
    
    
    do i=1, 100
        open(1, file = 'test.txt')
            write(1,*) i
        close(1)
    enddo
    
    end program handlesleak

1. Then compile by Visual Fortran Compiler 16.0, set breakpoint on line "open(...)" and look at with "Windows Task Manager" for number of handles. Number of open handles increases step by step.

2. Ok, now compile by previous Intel(R) Visual Fortran Compiler XE 15.0.2.179 and do the same steps. Number of handles does not increase.

Is it a bug of new compiler? And what to do to prevent leaks handles?

Yes, this looks the same as, https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/591225

I will associate your case with the internal tracking id, DPD200375683, to ensure we verify it against any fix.
