Oops, my report on that was not clear. Change the 1 to a 0 to get a different
ICE, at least in whatever random 3.4.0 snapshot I have installed (20040107).
It's apparently a 0/!0 thing. I have not checked this on a 3.4 release or
mainline, though. Here is the what I see after changing the 1 to a 0:
ice.c: In function `f':
ice.c:8: internal compiler error: in subreg_hard_regno, at emit-rtl.c:1026
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
