Reverting patches from this report:
http://sourceware.org/bugzilla/show_bug.cgi?id=13621
(modulo changes to linker.c since then) seem to fix the problem.
We're using gcc 4.6.3 and the ooops here happens when something hits the swap.
The similiar problem was spotted in Arch linux
https://bugs.archlinux.org/task/29694
and their solution was to remove the 13621 patch from arch binutils.
