------- Comment #3 from mikpe at it dot uu dot se 2009-08-06 15:58 -------
Reproduced on i686-linux with the following compiler versions and minimal sets
of options:
gcc-4.3-20090802: -O1 -fno-tree-dce
gcc-4.4-20090804: -O1 -fno-tree-ccp -fno-tree-dominator-opts
gcc-4.5-20090730: -O1
Note that 4.5 needed no -fno-... options to create the failure.
