This also crashes debug_tree on the decl from within the debugger. It seems
that lang_decl_name can do a fair amount of processing if v >= 2. Additionally
passing TFF_NO_FUNCTION_ARGUMENTS from there fixes the crash (and would be
sufficient for -fstack-usage), but this breaks __PRETTY_FUNCTION__ for example.
A possible solution would be to set TFF_NO_FUNCTION_ARGUMENTS if v == 2 and use
level 3 internally (in error.c and in pt.c for __PRETTY_FUNCTION__).
FWIW the Ada front-end doesn't print the arguments if v == 2.
