How to debug linux crashes

[KWo]

No problem. But even without -s (and without -o) near linking, I'm getting still the same info about crash (and nothing more). What is that "zone_shelter" in the drmingw report? It's always the same.

OK. Finally got crash saying this (it was compiled with MSVC++2005 and drmingw described it nice):

It happened when I was shooting at the bot sitting in some window.

[EDIT]
I think there is a need to check if (pBot->pShootBreakable<>NULL) before executing parts in case 1 and in case 2 in BotFindBreakable.
