Hi

The installation of todays CVS version (2003/05/01) produces a segmentation
fault on my Linux box. I use the following

SuSE Linux 8.0, i686

Python 2.2.2 (#1, Oct 17 2002, 08:48:02) 
[GCC 2.95.3 20010315 (SuSE)] on linux2

Numeric 23.0 (Release)

gcc version 3.2.3

running python under gdb gives:

(gdb) run setup.py install
Starting program: /usr/local/bin/python setup.py install

[Snip]

Does anybody see the problem? Is the new gcc version to blame?

Cheers Martin
