To: gcc-bugs
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.
