Patch to fix crashing experienced while using GDB

Hello,

Some time ago, I got the attached patch from jhb (IIRC). It has worked
for me and cured a problem that was making a bunch of my code
un-traceable using GDB on FreeBSD. Debugging would result in a crash of
GDB, preventing me from seeing what bug I had that crashed my program.

Anyhow, my question is: Is there any reason this shouldn't be pushed
into the tree? Who do I need to talk to (obrien? the compiler
maintainers?) about it?
