Summary	06933: adam: During Cassette Activity MAME Crashes With "Caught unhandled St9bad_alloc exception: std::bad_alloc" Message
Description	After "Game Over" under Donkey Kong Jr DDP, during soon to follow during cassette activity, MAME crashes with summary error.
Steps To Reproduce	1. Start up MAME with the adam driver loading a ddp image via command line: (I.E.) mame.exe adam -cass1 "C:\Path\to\Coleco ADAM DDP Images\Donkey Kong Jr (Coleco Adam).ddp" 2. Play a game where cassette loads game fully and the cassette load/play status no longer appears on screen (Typically within a couple of minutes of starting and playing a new game). 3. Allow game to end AKA "GAME OVER" message appears. 4. Now the following takes place automatiocally: -Tape plays/fast forwards until 25:45. -Tape rewinds. It hits 00:17. -Starts to play/ff again until it hits 00:36. -Rapid rewind. It goes to tape position 00:-4 (?) and crashes. -Both command line window and the MAME app window close out.
Additional Information	Another user was able to produce a crash with the Zaxxon game as well. "As soon as I lost all my ships and it flashed the blue screen with different game options, MAME closed itself with message: Caught unhandled St9bad_alloc exception: std::bad_alloc" See MAMEWorld posts: http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=375451 http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=375454 http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=375417

It is simply the mame64.exe executable renamed, and not the actual x86 executable. I have hundreds of shortcuts linked to batch files from many years ago that reference "mame.exe". After moving to 64-bit, it was simply easier to copy and rename the x64 executable rather than redo hundreds of shortcuts and batch files.

An error.log file was generated. It provides the following information: =================================== Soft reset [:net4:fdc:u6] ':net4:fdc:u6' (FA7A): unmapped io memory write to 103 = 00 & FF [:net5:fdc:u6] ':net5:fdc:u6' (FA7A): unmapped io memory write to 103 = 00 & FF =================================== The error.log file upload will follow
