Summary	04282: logicpro, logicpr2, karianx: Loading savestate causes MAME to segfault
Description	I made a savestate at a particular point in logicpro, specifically, at the "Final Select" screen (after completing all the initial puzzles). This savestate causes MAME to segfault. A second test savestate made immediately after starting the game does NOT cause a segfault upon loading.
Steps To Reproduce	Attempt to load the included savestate in the logicpro set. It should cause MAME to segfault (it does here).
Additional Information	Savestate 1 was made a ways into the game, and segfaults MAME upon loading. Savestate 2 was made immediately after booting the game, and loads properly.

Remember this is a MAME bug report board, if you have a request for the system, just ask me directly. It is intentional that you cannot upload a .sta file to prompt you to ZIP the file before you upload and reduce server bandwidth. Thanks.

I understand it is intentional that you must zip files before posting them (though the savestates only compressed by 1% each), but the report was that it said that it did NOT post successfully due to the error, when in fact it DID post, which lead to a double post, one without the uploaded file, and a second one with the uploaded file.

No.09189 NekoEd Senior Tester Dec 31, 2012, 15:50 edited on: Dec 31, 2012, 16:01	I only tested with logicpro (sans cheats, you can keep playing by pumping in more coins) and it seems to be fixed. I'll mark this one resolved, don't know what version, though. UPDATE: I tested logicpr2, but not as far in (after stage 4) and it did not crash. I think it's safe to consider this one resolved.
