No.03245 Fujix Administrator Dec 7, 2008, 11:57	It doesn't repro here with or without -debug, on 32-bit xp / 64-bit vista.
No.03246 Scagazza Tester Dec 7, 2008, 12:26	On my build pressing the cube button (spacebar) causes mame to quit too.
No.03250 Tafoid Administrator Dec 7, 2008, 16:57	There was an issue with the -cheat trigger in u4 - make sure you don't have that in your mame.ini as "cheat 1". I've tried and I cannot duplicate your report. on 32-bit, Windows 2000.
No.03251 Scagazza Tester Dec 7, 2008, 17:00	I have done some tests compiling at 64 bit with and without optimizations using MSVC and cubeqst crash; no problem with mingw32. My compiler is MSVC 2008 SP1.
No.03253 Tafoid Administrator Dec 7, 2008, 17:29	Scagazza, Over time, you have reported quite a few "unique to you" problems in the past (problems which were never reproduced by others). You should really try to discuss your found bugs with some other MAME users you might know before posting a report here again. Just be aware that constantly having to validate your errors which end up not being reproducible by anyone is a lot of wasted effort. Please consider this a warning. While we all make mistakes and have posted bad reports - it has happened far too often for you. Future bad reports might force us to take away reporting status. If you can, please reinstall from scratch your compilation system and build using the guidelines here: http://mamedev.org/devwiki/index.php/Building_MAME_using_Microsoft_Visual_Studio_compilers The only 'official' versions are Microsoft Visual Studio .NET 2003 and 2005 (according to MAMEDEV information). I know you said you used MSVC 2008, which might be the a source of some of your issues. As always, make sure you are building from only MAMEDEV.org sources, properly patched and built using only approved tools. Also, ensure that you are not carrying over object files from previous build - that will most assuredly cause unreproducible results. It might be worth seeing if someone else you know might be able to produce a 64-bit version for you to see if the same issues happen.
