Setting a breakpoint here and inspecting the arguments of
313 if (strcmp (proc->name, sym->name) == 0)
one can see that sym->name can be junk after the error message was emitted.
The place where sym is determined is a couple of lines above:
290 for (f = proc->formal; f; f = f->next)
291 {
292 gfc_array_spec *as;
293
294 sym = f->sym;
Either proc got corrupted or has not been set up properly.
On my x86_64 system I have:
(gdb) p *proc->formal->sym->name
$23 = 0 '\000'
