838.0. "Can't do "whatis" on a pointer field" by CXXC::MJHANS (Matthew Hanselman, DEC C) Thu Feb 13 1997 17:06
sym is a pointer
I can tell this because
a) I know it is a pointer before hand
b) Ladebug can tell me it's a pointer
c) I can print things out of the pointer
But ladebug won't let me "whatis" things out of the pointer. It tells me I'm
wrong.

(ladebug) whatis sym
a_symbol_ptr sym
(ladebug) whatis a_symbol_ptr

(ladebug) whatis sym->variant
Type of 'sym->variant' failed!
The type (a_symbol_ptr) is not a pointer type!
