[Bug c/13232] New: ICE in remember_web_was_spilled with -O3 -march=pentium4 -fnew-ra

[coyote at coyotegulch dot com]

The attached program generates an ICE, as follows:

scott@Tycho$ gcc -c -std=gnu99 -O3 -march=pentium4 -fnew-ra gcc-ice3.c
gcc-ice3.c: In function `planetpv':
 
gcc-ice3.c:29: internal compiler error: in subst_stack_regs_pat, at reg-stack.c:1580

Note comments in gcc-ice3.c. Initializing "k" elimintaes the ICE, as does
rewriting the loop from an infinite while to a do... while.
