I was able to catch a case on a debug server showing a "goal" is checked in AAS Botlib with a negative areanum:

Program received signal SIGSEGV, Segmentation fault.
0x000000000045b0eb in AAS_AreaDoNotEnter (areanum=-1038352384) at code/botlib/be_aas_reach.c:767


Server crash with caught signal
Clients are disconnected

  • I found it is easier to reproduce with 32 bits build engine than 64 bits build under linux. So I understand why it was first detected by windows users as the build is a 32 bits one. That sounds like a conversion problem but very hard to track.
  • Bot AI is really bugged in Smokin'Guns and will need to be re-worked at sometime
  • I committed in r367 a work-around to avoid the crash. The work-around verifies an index is not out of range and will output message in red color such as:
    Fatal: AAS_AreaReachability: areanum 1635413605 out of range
  • With the work-around, the bug is now major and won't block the v1.1b2 beta engine release
