Since 2006-12-05 the following test is failing (used to be PR 27768):
FAIL: g++.dg/opt/alias4.C execution test
According to the testresults mailing list, the bug appeared between
rev. 119481 ( http://gcc.gnu.org/ml/gcc-testresults/2006-12/msg00154.html )
and rev. 119532 ( http://gcc.gnu.org/ml/gcc-testresults/2006-12/msg00197.html )
The testcase works correctly with -fno-strict-aliasing.

------- Comment #1 from pinskia at gcc dot gnu dot org 2006-12-08 21:45 -------
This should have been fixed by:
2006-12-05 Daniel Berlin <dberlin@dberlin.org>
* tree-ssa-structalias.c (set_used_smts): Re-fix pr29156.
Optimize to avoid marking more SMT's as used when they aren't.

Fixed now, I don't know by what off hand but I think it was:
2006-12-11 Daniel Berlin <dberlin@dberlin.org>
* tree-ssa-structalias.c (handle_ptr_arith): Return false when we
can't handle the pointer arithmetic.
