Current gcc trunk (but not gcc 4.5.1) ICEs when linking cns_solve using -O2
-fwhopr -fwholeprogram. The reduced test case is attached and crashes as...

The lto1 ICE doesn't occur if the optimization is reduced to -O1 or if the
-fwhole-program flag is omitted.

This crash is distinct from the the resolved one from PR45037.
