No.10019 Tafoid Administrator Nov 27, 2013, 13:33	Make sure you have a .SYM file that matches the binary you are using - otherwise (which I think in your case), the output does not match the actual issue.
No.10021 B2K24 Senior Tester Nov 27, 2013, 15:51	Thanks for the tip. My output basically matches yours now, so I'll confirm this Exception at EIP=000000000161A590 (cli_frontend::execute(int, char**)+0x07a0): A CCESS VIOLATION
No.10215 etabeta Developer Jan 30, 2014, 05:27	this should be fixed in latest svn. while at it, I remind that "mess a800 -flop1 a" or "mess a800 -cart a" would reduce the best match output to the actual format you are interested. This is particularly useful when a system supports multiple softlists, since otherwise you cannot predict from which softlist a game is loaded... ;)
