| Additional Information |
Tracked down to a bug in mc6847 emulation, but only with mingw 5 and higher. These drivers have a character generator rom external to the mc6847, and use the callback MC6847_GET_CHARROM_MEMBER to read this rom. With the new tools, this callback is ignored, and it tries to use the internal characters instead. When it tries to display lowercase, the internal table overflows, causing the crash. Unfortunately, I do not understand the code being used in mc6847.cpp/h to operate MC6847_GET_CHARROM_MEMBER, so unable to fix it. I've only used 32-bit for testing, as I don't have a 64-bit build handy. |
