If you had used -fdump-tree-original, you knew that you created a simple local
procedure pointer, which is not in common and thus a NaN or a crash or ...
makes sense. Not surprisingly the culprit is the if (proc_pointer) {one line}
else { lots of lines } in trans-common.c.
How about the following patch?
$ svn revert trans-common.c
$ patch <<EOF
--- trans-types.c (Revision 140559)
+++ trans-types.c (Arbeitskopie)
@@ -1629,0 +1630,9 @@ gfc_sym_type (gfc_symbol * sym)
+ if (sym->attr.proc_pointer)
+ {
+ /* Unset proc_pointer as gfc_get_function_type calls gfc_sym_type. */
+ sym->attr.proc_pointer = 0;
+ type = build_pointer_type (gfc_get_function_type (sym));
+ sym->attr.proc_pointer = 1;
+ return type;
+ }
+
EOF
PS: You should reorder the items in COMMON as on x86-64 the pointers are
8-bytes wide, which causes a alignment/padding warning be printed.
