Please submit a full bug report,
(A guess is that the backtrace from xgcc is due to cc1 not ICE:ing but
SEGV:ing. Revisions at least around the mentioned range may instead consume
excessive memory; > 10 GiB, and are killed by the kernel OOM.)
Preprocessed t001_x.i and command-line is attached.
Author of all commits in the revision range CC:ed.
Note that when compiling any of the revisions r193595 .. r193667 on a host with
gcc-4.5 or earlier (possibly later versions as well) you need to apply revision
r193667.
