I reported a problem earlier about tclBlend 1.2.5 on Solaris 2.5.1
running TCL 8.2.2 and Sun JDK 1.2.2 where TCL interpreters are being
created and deleted repeatedly. Under this environment, TclBlend only
seems to work in the first couple of TCL interpreter creation and
deletion cycles then it crashes the application. I've been able to
obtain a stack dump of the crash:

It's pretty clear that a null pointer is being passed into
cacheAlloc() which is in libjvm.so. Unfortunately, I have no
information on the parameters passed into cacheAlloc(). Does anyone
know this information and/or have a clue why a null pointer is being
passed ?
Thanks,
George Wu
