Setting this to minor.

Author: kroartem Also setting --profile-laps=-1 makes stk crash. Auria and me don't think this is worth fixing.

[supertuxkart-sourceforge-migration]

Author: wardje Might be worth pointing out the second track you are inputting is an arena addon track. I don't seem to be able to reproduce it when using two normal ones. All that happens then is the second one of the two starting (with a slight delay for me compared to the AI).

[supertuxkart-sourceforge-migration]

Author: wardje The ''actual'' problem here seems to be that an arena track is started and subsequently AI karts get added to the race. Their controller tries to look for quadgraphs, which aren't (currently) defined in an arena.

For example, this produces the same error

gdb --args bin/supertuxkart --track battleisland -N

As such, I don't think the double --track parameter is actually relevant. Changing the title.

Author: kroartem Hiker said: 12:42 < hiker> Hmm -N for battle island just worked for me 12:43 < hiker> But I have artist debug mode set

However, it crashes for me both under linux (ubuntu 13.04 x86_64) and windows 7 (64-bit). I thought when it does else if (t->isArena()) race_manager->setMinorMode(RaceManager::MINOR_MODE_3_STRIKES); then everything is ok and it starts Three strikes battle, but I don't understand what happens next.

[supertuxkart-sourceforge-migration]

Author: kroartem Fixed this problem by enabling 0 ai karts for soccer and three strikes battle. Probably not the best solution, patch is in ticket https://sourceforge.net/apps/trac/supertuxkart/ticket/992
