Thanks for the report! I think we had seen this one before, but from what
I remembered, Will had already fixed all problems like this one. Apparently
the version I merged did not have the fix, so I applied the patch below
on top of my branch, and checked that it works on both sparc32 and sparc64.
Let me know if I should fix it differently.
