[Bug tree-optimization/28489] New: [4.2 regression] ICE in move_insn, at haifa-sched.c:1968

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I get the following ICE on ia64 with gcc 4.2.  Only happens at -O2, and doesn't
happen with gcc 4.0 or 4.1.

tbm@coconut0:~/delta/bin$ /usr/lib/gcc-snapshot/bin/gcc -c -O2 mini.c
mini.c: In function 'PL_next_solution':

mini.c:119: warning: cast to pointer from integer of different size
mini.c:187: warning: assignment makes pointer from integer without a cast
mini.c:216: internal compiler error: in move_insn, at haifa-sched.c:1968
