This doesn't seem to be a problem on freebsd 8.

I've forced -Xint on in my build now so I can't confirm the current
behaviour but I don't imagine the situation has changed.

I've run some classlib tests with -Xint and the appended patch and
uploaded my results to:


The patch fixes some socket issues but there are more socket issues and
there are also several other problems with crashed tests.  I'm planning
to investigate these further.

The same patch fixes some of the socket issues on x86_64 too but it
doesn't seem to fix quite as much as on x86.  I'm going to look at this
as well.

Cool.  I'm concentrating on classlib problems at the moment because I'm
interested in portability improvements in this code but obviously the
VM/jit issues are pretty crucial to making real progress.


P.S.  We are in code freeze so I don't plan to commit this and it
      needs tidying up before it could be committed anyway.
