So this is wx source, line 56?

I don't see that in the newer wx source, they re-arranged the source.

src/common/evtloopcmn.cpp, line 59 has this:

    // event loops are not recursive, you need to create another loop!
    wxCHECK_MSG( !IsInsideRun(), -1, wxT("can't reenter a message loop") );

But its not firing.
