--- Comment #11 from Torbjörn Gard <tgard at opentext dot com> ---
No failure but restarted it in /home/tga01/obj_gcc with the thought of having a
shorter and simpler path.

            Bug ID: 61035
           Summary: Crash in getcwd intrinsic due to stack overflow
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: libfortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jb at gcc dot gnu.org

The example program below crashes (my stack size limit is 8 MiB).

program getcwd_overflow
  implicit none
  character(len\x10485760) :: str ! 10 MiB
  call getcwd(str)
  print *, trim(str)
end program getcwd_overflow

The reason is that in libgfortran/intrinsics/getcwd.c we try to allocate space
for a NULL-terminated duplicate of the string on the stack.
