--- Comment #16 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
FWIW it also segfaults on:

  write(unit=3D6, nml=3Dnam_bu_ru)

I have been digging around with gdb in trans-io.c and I can see the cl is 0=
x0
in the sym->ts.u.cl and I can find nothing else accessible at this point. I
think I am going to have to go back to the "trans" for the allocate which
should have the length resolved and stuff it into the sym.=
