Responsible-Changed-Why:
    This problem is probably in your domain.
    
    Can you fix that on the 3.3 branch or is this pure 3.4 stuff
    (where it is fixed already)?
    
    BTW, I now get an ICE on the 3.3 branch (as of 20030502):
    PR8878.c: In function `main':
    PR8878.c:18: internal compiler error: in subreg_hard_regno, at emit-rtl.c:931
    Please submit a full bug report, [etc.]
