tracing crash

[Nir Aides]

Hi,

I am facing a strange problem.
I will appreciate an explanation and a work around for the problem.

Look in the following code paste. It seems that taking a reference to 
the frame object crashes python in some scripts:

#
# trace_hell.py
#
# crashes with spe (stani's python editor) v0.7.3.a
#
# to see the crash add "import trace_hell; trace_hell.unleash_hell()" as
# the first line in spe.py
#
# 1. The statement that triggers the crash is "g_frame = frame"
#

import sys

g_frame = None

def tracer(frame, event, arg):
     global g_frame
     g_frame = frame
     return None

def unleash_hell():
     sys.settrace(tracer)
