The following ACATS started failing:

PASS: LAST_UPDATED: Fri Jan 29 14:43:55 UTC 2010 (revision 156351)

FAIL: LAST_UPDATED: Sat Jan 30 14:08:06 UTC 2010 (revision 156383)
http://gcc.gnu.org/ml/gcc-testresults/2010-01/msg02859.html

It has been consistently FAILing since.

Likely patch from looking at ChangeLog:

+2010-01-29  Eric Botcazou  <ebotcazou@adacore.com>
+
+       * tree-ssa-alias.c (same_type_for_tbaa): Return -1 if the types have
+       the same alias set and their sizes different constantness.
+       (aliasing_component_refs_p): Revert 2009-10-24 change.

I do not see it FAILing on other platforms.
