    Confirmed. Worked with 2.95, so is a regression.
    
    Stefan, if you want to help us greatly, try to reduce the
    code further, by first using -save-temps to get rid
    of what the preprocessor does, then delete all the lines
    starting with a '#', and then chip away whatever is not
    needed to demonstrate the bug. We need to find out which
    function exactly is being miscompiled, and the present
    testcase is too large for this, so it would take us some
    time. If you could try to get it smaller, that would be
    greatly appreciated!
    
    Thanks
      Wolfgang
