Works with 4.3.1.  Should this be closed if someone can confirm it is fixed on
the trunk?

This is a generic m68k issue as I can easily reproduce the ICE using a
gcc-4.2.4 based cross-compiler to m68k-unknown-linux. The current latest
gcc-4.4 and gcc-4.3 weekly snapshots do not exhibit the ICE however.

No longer reproducible, assuming fixed.
