Hello Roger,

thanks for the initial report,
but we could use some more information on what your program is doing
(a rpython traceback is simply not enough of a clue to guess the problem)

also it would be helpful, if you tried if the code works correct on a nightly build.

Since you run on windows, also try on a linux to rule out platform issues.

Fatal RPython error: MemoryError

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.



At first I thought it was pypy reporting that the PPM compressor had ran out of 
memory, and simply didn't report the app's stack frames.  But I've since come 
to realize that normally pypy does report a MemoryError and the stack frames 
involved, just like Python, and that this case was instead a RPython crash.

I'm hoping the above stack trace from pypy is enough of a clue.

pypy -v
