Hope this is the cause of the mystery crashes and it can be traced. Hopefully not back at my environment being fucked.
Try a clean SVN (no munt stuff) and without debug first.
The MSG_Add code seems okay to me at first glance. (where your backtrace points at)
It isn't the first time when this function is called either ( which is with CONFIG_FULLSCREEN )
Yup. I changed the main config file to set core to simple and started with ./dosbox -userconf (although i can't scroll up to see if the config file chosen is the right one because the debugger window cleared the console).
edit: i think the output of configure might be showing the problem.

is that "checking host system type... x86_64-unknown-linux-gnu" thing normal? Wasn't it p much supposed to pinpoint my cpu type at least?

For what it's worth i managed to run the Azrael's Tear bug through a debugger (with normal svn - without patches, just built locally with ./autogen; ./configure; make - non-debug dosbox for obvious reasons). It gave me this

It's semi random, but happens p quick most times. Often just in the first room less often in the 3rd or 4th room after shooting a guy and speaking to another guy. It seems to happen often when speaking to that guy if it didn't in the first room. You can also wait on the first room and it seems most time it crashes (probably due to the critters moving around).
I was playing with dos32a replacing the packed dos4g, but it also happens in the untouched executable install.
Dosbox 0.74-4 from the repositories doesn't have this problem
yeah. I added that exit condition. I am surprised it triggers in a real game, so maybe some fpu register isn't cleared by dosbox correctly. Or they would rely on the stack overflow exception, but I don't see why a game would do that as it isn't the greatest for speed.
I did find that the game doesn't crash with 32bits dosbox (my ppa build). But i think it's still a regression, since it didn't either with (i believe, because i never specified :i386) dosbox 0.74-4 64 bits build from the ubuntu repositories.
Yeah. I have to see if I can find the game.
The game regressed, but the exit condition that was added, makes sense. So maybe something else is going wrong.
