[Guppy-pe-list] getting a core dump when using gyppy

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi everyone,
So here's the description of the problem also listed here:

<http://stackoverflow.com/questions/6796714/segfault-when-using-guppy-heapy>
So I am using Python Stackless with heapy on two diffrent machines with the
same architectures but slightly different C compilers. Heapy works perfectly
fine on the first one, but I get a core dump on the second one.
Python 2.7.1 Stackless 3.1b3 060516 (release27-maint, Jul 20 2011, 13:26:38)

[GCC 3.4.3 (MontaVista 3.4.3-25.0.116.0601565 2006-09-20)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> from guppy import hpy;
>>> h=hpy()
>>> h.heap()
Segmentation fault (core dumped)

I don't know how to tackle this problem. Any suggestions appreciated.
In case you were wondering, this is how it looks in the other one that
works:

here is the gdb output of the one the segfaults me:
