Background animation broken in SVN

[yufra]

I compiled revision 1534, and on a whim enabled the background animation again. The game froze fairly quickly, and the last few lines in stdout were:

Code: Select all

player	1	dumb ai talents can use	Fireflash	T_FIREFLASH
player	1	dumb ai talents can use	Flame	T_FLAME
player	1	dumb ai talents can use	Sunshield	T_SUNSHIELD
player	1	dumb ai talents can use	Manathrust	T_MANATHRUST
player	1	dumb ai talents can use	Lightning	T_LIGHTNING
dumb ai uses	T_LIGHTNING
USING	table: 0x5df990	Lightning

I have also seen it crash/hang on T_MANATHRUST, so maybe it is targeting? Then again I haven't seen it succeed on any, so maybe it is particles... no idea. Can others reproduce this?

Froze ? hum
Can you try to gdb it ?

I launched it within GDB but there is no stacktrace to catch... my initial diagnosis is an infinite Lua loop or something to that effect. No errors are thrown, the program does not quit and the only way to recover is to force quit. Here is the stack after I force quited (not sure if that is useful):

[darkgod]

Hum can you try putting in some debug print() to see where it loops?
Obviously this works here :/

[yufra]

I'll put it on the to-do list.

[yufra]

Ah, of course... it had something to do with the tinkering I was doing in ActorTalents, an infinite recursion that for some reason wasn't causing a stack overflow (or not quickly enough?). Anyway, ignore this.
