That seems overly enthusiastic -- if we're not optimizing, who cares?
(When we zap TYHPE_METHODS we currently set it to error_mark_node, if it
was non-null, so that this above check will work).
As a result gdb was unable to do an inferior call to its the object's
methods.
Right, I realize I failed to mention gdb in the email. To be clear, what the
snippet does is NEVER put record types in registers, when not optimizing.
