Issue222851

After successfully (seemingly!) installing Jpython1.1 on my SGI Indego2 whenever
I 
try to start the interactive interpreter or run any script Jpython crashes with
the 
traceback given below. 

Going back and trying previous versions of Jpython I found that everything
works
fine upto and including version 1.1b3.

213% ./jpython

    si_signo [11]: SIGSEGV   11*  segmentation violation
    si_errno [0]: Error 0

Thread Alarm Q:

I will look at this again if it still exists on jython. Closing the bug report for now.
