What happens if a binary compiled with GCC/DW2 calls a C++ function in a Dll compiled with MSVC and this function throws an exception? > > > _______________________________________________ > Development mailing list > Development@qt-project.org > http://lists.qt-project.org/mailman/listinfo/development > _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
