I am writing a compiler/translator that uses JPython
as a backend. In this application the size of the generated
code gets very large and I have found out that JPython
crashes with the following error under some circumstances:

Traceback (innermost last):

Please note that this is not a problem for me anymore because 
I have rewritten my code in such a way that the problem 
dissappear but I think it is a good thing for you to know
that there seems to be a problem when the code size gets big 
in JPython.

Basically what I did was to change calls like this:
    add_output_values(("EbcIo",EbcIo))
into:
    add_output_values("EbcIo",EbcIo)
and then the problem is not there anymore.

If you remove some of the calls to add_output_values the problem 
also goes away.

I have confirmed this problem under Solaris JDK 1.1.5 and Win NT JDK 1.2.1.

Here is the code that gives me the problem. It is very large but
since this problem probably has with the size to do I have chosed
to post it anyway:
