Many thanks Tom and David.

We will try to upgrade to supported version.

Yeah, that would certainly be the first thing to try.  If the problem is
still there, we'd really need quite a bit more information to diagnose
it.  A stack trace from the point of the crash would be quite helpful:

Even better would be if you can reduce the problem to a self-contained
test case, though I realize that might be hard.
