Hi there,

I seem to be running into a problem with freeing memory.

Under OS X all is well, but under Linux there seems to be a problem in the case of linked data structures.

I have attached a python program which demonstrates the problem. The output of the script for both linux and OS X are below.

Thanks very much in advance, and for the amazing work on PyPy.

OS X:
