That's pretty weird. I can reproduce this with most a 3.4 snapshot from
2003-05-15 as well as a 3.3 snapshot from 2003-05-16. I compared the
assembler output, and instructionwise they are equal, but there are some
additional linkonce things in your output. I don't know enough about this
stuff to tell whether that's relevant.
I'll update now to present HEAD and check+report again once the bootstrap
is done.
