It looks like there is something left over from PRE in the phi nodes for a block:

This is the first PHI node for the block:
p print_generic_stmt (stderr, $6, 64)
 EUSE () [class:-1 phiop:1 bb:7685 ]

Err, PRE doesn't put anything in the phi_nodes chain, so this is certainly strange. I'll see what's up. :P

If you compile with -fno-tree-pre the program finishes compilation.
