It might have appeared to work in a 3.2 source tree.  The way
exception handling interacts with threads under VxWorks has changed
between 3.2 and the mainline.  You were making changes to get the
patch applied to the mainline, so you should have done a proper retest
on the mainline.

There were other problems with the patch that should have shown up
under 3.2 as well, but they were not as serious.
