From: Lars Uffmann on
Okay, I have tracked this down to be a MinGW problem, after using the
MinGW 5.1.6 installer to build wxWidgets 2.8.11 stable release,
wxWidgets sampleMinimal runs perfectly fine.

So in summary, I will move this thread into the MinGW mailing lists, and
would like to issue a WARNING to everyone considering to use any later
MinGW packages than distributed in the 5.1.6 packaged installer: At
least one of those packages has a severe bug that is a showstopper for
wxWidgets!

Best Regards,

Lars
