Well, I can't say anything about "heavily tested with wx-2.6.3", because I use wx-CVS, which gives me some headaches from time to time, but I believe I can be more productive making sure aMule will always run on the latest wx code.
As for debug info, yes, debug is included by default on hand configured code. But give another check, because it might have been stripped if you use someone else's script. It is just that I saw no debug symbols in your code, either from aMule or wx.
BTW, your problem seems related to wx. Can you post the configure line you used to compile it?
Cheers!
