Another thing : If the 'float' is initialised with a float constant directly (i.e. "foo=3.3333", instead of filling in directly the IEEE hex representation of the float through casting and indirections), no problem occurs, which could mean (writing as I am thinking) a problem exists in the machine description for SSE capable machines, leading the various insn shufflings to loose the track of the variable state (forgetting that (int)foo is dependent on foo - and this possibly happens because 'foo' is never an lvalue - although *&foo is) --Ivan -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17394
