When using gdb-309 and gdb-370 on MacOS X 10.3.9, even the simplest queries seem
broken.
On stage2 gengtype, I get
scientist:~/cvs/gcc/build/gcc bonzinip$ gdb build/gengtype
(gdb) b mangle_macro_name
Breakpoint 5 at 0x8458: file ../../gcc/gengtype-lex.l, line 429.
(gdb) run
Breakpoint 5, mangle_macro_name ([snip]) at ../../gcc/gengtype-lex.l:429
(gdb) fini

263 t = find_structure (ptr, 0);
Value returned is $1 = 0x11ccb0 "VEC_tree"
(gdb) p ptr
No symbol "ptr" in current context.
...
228 for (s = structures; s != NULL; s = s->next)
(gdb) p structures
$2 = <unknown type>
...
106 for (p = typedefs; p != NULL; p = p->next)
(gdb) p typedefs
$5 = <unknown type>
and so on.
