Let's rewind just a little.  What I was recommending was to determine if the crash is
happening in a static destructor or not.  Again "static destructor or not."  THis is a yes
or no question, with only one of two possible answers.

If the crash happens after main() then, its in a static destructor, else not.  Again, only
two choices.

Yes, you can inline expand the macro IMPLEMENT_APP() without recompiling wxWidgets.  Just
look at the header where it is defined, and put that code in place of the macro in
single_top.cpp

And instrument the bottom of main() with a printf that will hopefully get you the answer
to this YES/NO question.
