[Bug fortran/42900] New: gfortran.dg/stat_[12].f90 may fail on NFS filesystems

[ro at gcc dot gnu dot org]

I've noticed that all the gfortran.dg/stat_[12].f90 fail for me on all
platforms
(i.e. sparc-sun-solaris2, alpha-dec-osf, mips-sgi-irix).

FAIL: gfortran.dg/stat_1.f90  -O0  execution test

at all optimization levels.  Running it under gdb reveals that it aborts here:

#4  0x000110f0 in MAIN__ ()
    at /vol/gcc/src/hg/trunk/solaris/gcc/testsuite/gfortran.dg/stat_1.f90:19
19        if (s1(6) /= getgid() .and. getgid() /= 0) call abort

Unfortunately, the test is bogus: at least on NFS with either the sgid bit set
on the parent directory or with the filesystem mounted with the grpid option,
newly created files are created with the gid of the directory, not the primary
group of the owner.

I don't know how best to fix this (maybe check if the file's group is in the 
set of supplemental groups, if libgfortran supports getgroups).

I'd say add a comment to the testcase and WONTFIX.

I don't think this is a good idea: this part of the testcase tests a
condition that doesn't necessarily hold, and is outside the control of
the testsuite.  I'd rather remove that part of the test than have this
confusing noise in many reports.
