This seems to be the same problem that had been reported in Gentoo and
upstream, see [0], [1]. Could you please try the following patch, taken
from the Emacs trunk? It should fix the failure, but since the segfault
only happens in ~ 1% of all builds it would be good to try building
emacs22 a few hundred times with and without the patch.
