* gdb.trace/unavailable.cc (struct Virtual): New.
(virtualp): New global pointer.
* gdb.trace/unavailable.exp (gdb_collect_globals_test): Test
printing a pointer to an object whose type has a vtable, with
print object on.
gdb/
* value.h (value_entirely_available): Declare.
* value.c (value_entirely_available): New function.
* c-valprint.c (c_value_print): Don't try fetching the pointer's
real type if the pointer is unavailable.
