What did you expect?  After all, GDB runs in the same process as the
debuggee, right?

Can't you fix the problem (by committing the page) before returning?
The ``cannot continue'' problem is easy to work around (just longjmp
instead of returning), but you need to fix the cause of the exception
first.

I'm afraid I don't have a clear idea of what you wanted to do,
though.  Suppose the debugger weren't crashing: what did you want to
do then?  Why did you try to access the uncommitted page in the first
place?
