From the patch, I think the PR number is wrong and should be 69955.

The test fails on darwin with

At line 71 of file /opt/gcc/work/gcc/testsuite/gfortran.dg/pr69955.f90 (unit = 21)
Fortran runtime error: Cannot open file '/proc/974/statm': No such file or directory

Thanks for working on this issue,

Dominique
