Re: [Matplotlib-users] MPL 1.2.0 crash with py2exe on Athlon PC

[Werner F. B. <wer...@fr...>]

Hi,

Did some more testing with the 
"http://matplotlib.org/examples/user_interfaces/embedding_in_wx5.html" 
example and see the same problem/crash.

Attached the slightly adapted version of the script (using wxPython 2.9 
and wx.App instead of wx.SimpleApp which is deprecated in 2.9) and the 
setup.py script I used to generated the py2exe'd version.

The py2exe'd version works without problem on my Intel Core i5 but 
crashes on an AMD Athlon 2400+ equiped PC.

Anyone has some tips, ideas on how to track this down?

Best regards
Werner
