I see this too, for cris-elf, but for 931004-6.c as well.
I'm going to assume it's the same bug (and relevant in this PR)
for two reasons: due to the failure being at -O3:

FAIL: gcc.c-torture/execute/931004-2.c execution,  -O3 -fomit-frame-pointer
-funroll-loops
FAIL: gcc.c-torture/execute/931004-2.c execution,  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions
FAIL: gcc.c-torture/execute/931004-6.c execution,  -O3 -fomit-frame-pointer
-funroll-loops
FAIL: gcc.c-torture/execute/931004-6.c execution,  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions

(the gcc.log says "program stopped with signal 6." hence an abort call)
and because of the timeframe for the appearance of the failure:
the tests worked with LAST_UPDATED "Fri Apr  8 17:09:07 UTC 2005"
and started failing with "Sat Apr  9 01:52:04 UTC 2005".

Appeared on hppa64-hpux between 2005-04-09 01:34 UTC and 2005-04-09 01:38 UTC. 
I.e., caused by tree-cleanup-branch merge.

Started to pass again on hppa64-hpux between 20050422 and 20050423, could it be
confirmed whether they pass again on cris-elf as well?

Most likely fixed by:
+2005-04-22  Diego Novillo  <dnovillo@redhat.com>
+
+       * tree-cfg.c (tree_duplicate_bb): Call create_new_def_for
+       for newly created PHI nodes.
+       Call create_new_def_for for every new V_MAY_DEF and
+       V_MUST_DEF on the copied statement.
+       (struct ssa_name_map_entry): Remove.
+       (ssa_name_map_entry_hash): Remove.
+       (ssa_name_map_entry_eq): Remove.
+       (allocate_ssa_names): Remove.
+       (rewrite_to_new_ssa_names_def): Remove.
....
Then. Closing as fixed.
