Game crash with error: "Assertion failed!"

<< < (2/2)

teej:
I am also suffering from this crash. 2.1.1. It was the most recent Win32 from sourceforge on May 4th 2007. Version confesses "2.1.1 x86 May 1 2007 Win32 DEBUG"

I can produce it regularly, and can also avoid it regularly by calling back my original dropship and deploying another.

Looks like the line number in cl_team differs now to 613.

Part of my ufoconsole.log follows.

here you can see the offending procedure from cl_team.c, lines 588 - 625.
assert(cp); is the implicated failure.

/* holster, backpack) at the top level, i.e. each squad member reloads */
/* her right hand, then each reloads his left hand, etc. The effect */
/* of this is that when things are tight, everyone has the opportunity */
/* to get their preferred weapon(s) loaded before anyone is allowed */

/* leaving others with unloaded guns in their hands... */

Zenerka:
In current trunk the offending function, that is CL_ReloadAndRemoveCarried(), is rewritten to the more sane way, that is no more baseCurrent usage there (and this is the real source of the problem, because the pointers of baseCurrent and current team are sometimes not synced).
Unfortunately there was not enough time to test it properly and merge to 2.1.1, so we have to live with that assert from time to time.
Also such problem can be avoided by sending only one dropship to desired mission at one time directly from the base (without save/load in the middle).
