I ran your test on my version of the fix. I don't see any crash. One
difference in my code is that I didn't remove any of the reference counting
code that was in the C part of TclBlend. I.e. when a Tcl_Obj is created to
wrap a TclObject, it adds a ref count. Theoretically, this is not needed
s
. But
with this fix, it makes life much easier to write Tcl commands in Java.

In TclBlend 1.2.6, when a ReflectObject is created to represent a TclObject,
the ReflectObject does not preserve() the TclObject. But the ReflectObject
holds on to the TclObject for a long duration in its hash table. When the
TclObject is dereferenced, it can cause the ReflectObject to contain a
