Thanks for the tip. I am going to install the 64 bit version and recompile wxpython and see what happens. 

I had a reason for doing the 32 bit version but I don’t think it matters.

Hi Brian,

There is a long litany of things that can go wrong with msys2 builds but
I do not believe that the wxPython/wxWidgets mismatch is the problem.
Typically when I see issues like this, there has been a new gcc version
released and only one of the two dependency libraries have been compiled
with the new compiler which causes issues.  It's been a while but the
last time this happened, I had to recompile the wxPython package.  I
also noticed you are attempting to use 32 builds for debugging.  I
highly recommend that you debug using 64 bit builds.  Debug builds on
msys2 are massive and you will likely run into memory limit issues.  I
hope this helps.

Cheers,

Wayne
