[pypy-dev] pypy MemoryError crash

[Roger Flores]

Hello all.  A bug in a python application of mine resulted in this pypy crash:

RPython traceback:

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.
