Not to my knowledge.

I don't think so.
The current behavior is very non-intuitive.
As a person who hacks gdb, the kernel, and the interactions between
them extensively, it took even me quite a while to track down this
problem.
Imagine some less skilled person trying to analyze a core dump
expecting the necessary information to be there and being unable
to figure out why?
So I'd say we should just put this change in, as-is. It fixes bugs,
and in all the time that has passed since my initial posting there
has not been any serious dissent.
