My understanding is that gcc 3.2.3 should have a few m68k bug fixes 
and this is one of them.  

An RTEMS 3.2.3 patch will be available soon I hope.  I am waiting for 
the patch for Angelo's illegal instruction on the i386 problem to settle 
on the 3.3 branch so I cna put it in our patch.

I have a test set of 3.2.3 binaries installed.  What RTEMS configuration
options were you using ot get to that point?  I can try to see if it is
fixed.
