No. It's in 64 bit that it crashes. I have not tried recently with wx 30 in 32 bits.

PS : I've just tried in 32 bit. No crashes at startup, but a message already seen :
wxWidgets Debug Alert
../../src/msw/bitmap.cpp(820) :assert "image.IsOk()" failed in CreateFromImage(): invalid image
But my wxWidgets is created as a "release" version not a "debug" one. And if I build wxWidgets by adding DEBUG_FLAG=0, as in Xaviou's version for tdm 4.8.1 (64 or 32 bit), when I build C::B, it claims at link time that some references are missing (those concerning assert). (by default DEBUG_FLAG is set to 1 apparently, even in a release version).
