Anyone know anything about the gdb internals with respect to .debug_frame?

I have the specs - the trouble is, gdb appears to show a correct 
backtrace regardless of whether the .debug_frame section is emitted or 
not. So what does gdb need it for?

When I was working on the GDB patch, I was on the a GDB mailing list.  I
found the list to be very friendly and helpful.  I would recommend asking
there if you're working on some DWARF output!

If you do join one of the lists, let me know and I'll hop on as well, since
I'd like to further the D patch for GDB to support anything D needs it to.
