Just finished bootstrap on x86_64-*-freebsd.

% gmake -j7 check-fortran

                === gfortran Summary ===

# of expected passes            54886
# of unexpected failures        3
# of expected failures          193
# of unsupported tests          110


% gmake check-fortran RUNTESTFLAGS="cas.exp=\*.f\*"
                === gfortran Summary ===

# of expected passes            65
# of unsupported tests          2
objs/gcc/gfortran  version 11.0.0 20201025 (experimental) (GCC) 


So, the issue I've reported else thread is likely a
32-bit vs 64-bit OS issue.  Perhaps, a size_t or
ssize_t issue?

% cat a.c
#include <stdio.h>
int
main(void)
{
   printf("%d\n", sizeof(size_t));
   printf("%d\n", sizeof(ssize_t));
   return 0;
}

On i386-*-freebsd
% cc -o z a.c
% ./z
4
4

On x86_64-*-freebsd
%  cc -o z a.c
% ./z
8
