It's the most strange thing that the revision number of the nightly I previously used is 13311, too.
The steps to reproduce:
Create a new wxWidgets project, and select wxWidgets 3.2. Specify project name, and project directory. GUI Builder is wxSmith, and the app is frame based. Uncheck the Debug configuration, because I've not built it. Then, select use dll, monolithic library, enable Unicode, and empty project. Click Next. At this time, the error occurs.
The attached file contains script.
Edit:
For the compiler use LLVM Clang Compiler, this is the only difference than the previous.
