[wxPython] wxPython 2.3.2 (Linux) glcanvas

configuring wxGTK with --enable-debug and see if
there is any assert or failure message that can help.

I'll try.

There is no message when I execute wxGLCanvs.py.(And GL fails)

But when I execute wxGTK-2.3.2/samples/opengl/cube/cube.cpp,
there is the fallowing message and core dumped.
( When using wxGTK without --enable-debug, cube.cpp works Okay. )
Why?

17:01:05: Debug: Assert failed in file ../src/common/object.cpp at line 249:
an infinite loop detected - have you used IMPLEMENT_DYNAMIC_CLASS() twice
(may be by linking some object module(s) twice)?
??? (core dumped)
