dwarf2read.c:5468: internal-error: could not find partial DIE in cache

A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) n

Create a core file of GDB? (y or n) n

Thereafter, trying to debug results in all sorts of nastiness:

Warning:
Cannot insert breakpoint 0.
Error accessing memory address 0x0: Input/output error.

Red Hat have a patch for this; the commit to Fedora is
https://www.redhat.com/archives/fedora-cvs-commits/2005-May/msg00100.html

The patch needs a small amount of massaging to apply to Gentoo gdb 6.4-r1. I
attach the adjusted patch, which corrects the bug.

Suggest the patch be added to Gentoo tree.

added to 6.4-r2, thanks for the info
