[Python-Dev] segmentation fault with python2.3a0 from cvs

[Gerson Kurz]

Hi folks,

yesterday I posted a problem with importing a very large sourcefile in
python 2.2.1 to clp. For the original report, see
<news:3da070ec.18868296@news.t-online.de>. Andrew MacIntyre 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. Now, instead of just a
MemoryError, I get this:

$ python
Python 2.3a0 (#1, Oct  7 2002, 18:49:14)
[GCC 2.95.3-5 (cygwin special)] on cygwin
Type "help", "copyright", "credits" or "license" for more informatio
>>> import test
Traceback (most recent call last):
Segmentation fault (core dumped)

The stackdump reads

So I guess its back in your (aka Developers) corner. 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).
