Summary: segmentation fault importing huge source

Initial Comment:
I posted a problem with importing a very large sourcefile 
in python 2.2.1 to clp, see 
<news:3da070ec.18868296@news.t-online.de>. 
Someone suggested that 2.3 would handle this situation 
much better, so I got the current version from CVS, built 
it with cygwin and tested it. That version raises a 
segmentation fault. The stackdump shows an 
ACCESS_VIOLATION somewhere inside python2.3.exe.

You can download the source that causes this at

http://p-nand-q.com/python/toobigfor2.3.zip

but beware, the zipped source is 613k large (unzipped 
around 4.2 mb).

Do you know where python crashed?  My guess was after a
failed malloc.  I tried testing this, but I don't have
enough memory/cpu/patience to wait for loading such a large
file.  Can you make the test case smaller?  What is the
minimum size that still causes the seg fault?  What version
of cygwin?  There is a known malloc problem in 1.3.12, see
http://sources.redhat.com/ml/newlib/2002/msg00369.html
