FYI, we are having to make a change in Insight to cope with a funny
thing that recently appeared in GDB.
The target type of a void* does not have the type name set to "void" any
longer.
(gdb) p *type
$3 = {code = TYPE_CODE_PTR, name = 0x0, tag_name = 0x0, length = 4,
upper_bound_type = 0, lower_bound_type = 0, objfile = 0x854e998,
target_type = 0x8bcd5d8, pointer_type = 0x0, reference_type = 0x0,
cv_type = 0x8bcd61c, flags = 1, nfields = 0, fields = 0x0,
vptr_basetype = 0x0, vptr_fieldno = -1, type_specific = {arg_types =
0x0,
cplus_stuff = 0x0}}
(gdb) p *target
$4 = {code = TYPE_CODE_VOID, name = 0x0, tag_name = 0x0, length = 1,
upper_bound_type = 0, lower_bound_type = 0, objfile = 0x854e998,
target_type = 0x0, pointer_type = 0x8bcd61c, reference_type = 0x0,
cv_type = 0x8bcd5d8, flags = 0, nfields = 0, fields = 0x0,
vptr_basetype = 0x0, vptr_fieldno = -1, type_specific = {arg_types =
0x0,
cplus_stuff = 0x0}}
As you see, TYPE_CODE_VOID does not have a name anymore, at least when
it is the target of a (void *) type..
