[Bug fortran/40011] Problems with -fwhole-file

[rguenth at gcc dot gnu dot org]

------- Comment #36 from rguenth at gcc dot gnu dot org  2009-07-24 10:24 -------
With the newest whole-file patch I instead get

#1  0x087a1c89 in tree_check_failed (node=0xb6e9fcb0, 
    file=0x8b9d398 "/home/richard/src/trunk/gcc/fortran/trans-types.c", 
    line=2010, function=0x8b9da9d "gfc_get_derived_type")
    at /home/richard/src/trunk/gcc/tree.c:7460
7460      internal_error ("tree check: %s, have %s in %s, at %s:%d",
(gdb) 
#2  0x081e2850 in gfc_get_derived_type (derived=0x136519f0)
    at /home/richard/src/trunk/gcc/fortran/trans-types.c:2010
2010          if (TYPE_FIELDS (derived->backend_decl))

with derived->backend_decl looking like random crap.
(in fact it seems to be GC collected memory, all 0xa5a5a5a5).

All of gfortran.h seems to be ignorant of the GC - which means we may
not garbage collect while the FE is still running, so all calls to
cgraph_finalize_function should have true as their 2nd argument.
