I verified the testcase detects the problem on both gcc-3.3.1
and on gcc-3.4-20030903, but on my system, I have to use -O2.
With -O1, the testcase does not report failure.
I also verified that this is a regression from both
hardhat 2.0 gcc-2.97 and dodes gcc-3.0.2.
I will submit a patch to add the test to the test suite.
