Public bug reported:
The recent gdb upload
https://launchpad.net/ubuntu/+source/gdb/7.4-2012.02-0ubuntu1 disabled
the patch gdb-7.2-gcore-relro-writer.patch which was added to address
bug 680588. The reason the patch was disabled was because it no longer
cleanly applies to the gdb source tree; the gdb/linux-nat.c source file
is significantly different in the 7.4-2012.02 version.
I've confirmed that an updated version of the patch is still necessary;
with 7.4-2012.02-0ubuntu1 backtraces like the following are generated:
(gdb) bt
#0 0x00007fda019b82b0 in ?? ()
#1 0x00007fda019b816c in ?? ()
#2 0x0000000000000000 in ?? ()
