I may have found a way to reproduce the problem without libgomp (disclaimer: I
have no idea whether this testcase if valid fortran or not).
Consider this testcase:
...
implicit none
integer(kind=4) z
call foo (z)
contains
subroutine foo (a)
type (*), dimension (..), contiguous :: a
print *, sizeof(a)
end subroutine foo
end program
...
compiled like this:
...
$ gfortran -O2 test.f90
...
gives:
...
$ ./a.out
8
...
Previously, the testcase printed 4 instead of 8.
