[Bug fortran/45077] ICE with -fwhole-file in fold_convert_loc, at fold-const.c:2021

[burnus at gcc dot gnu dot org]

------- Comment #2 from burnus at gcc dot gnu dot org  2010-07-28 07:43 -------
Patch. Note: It still fails if one moves "module iso_red" into a separate file.
Cf. PR 44945. The reason is that then "gsym" will come up as NULL and every
module user uses a different decl.
