| Summary | 0000273: crash on Group AI deconstruction | ||||
| Description | When clearing a groupAI that can be given orders (such as the Simple Formation or Central Build AIs), Spring crashes. When clearing a groupAI that cannot be given orders (such as the RadarAI or the MetalMaker AI), everything's fine. To be clear: this concerns commands the user can give to the groupAI, and not about commands the groupAI gives to its units. That is, IAICallback->GiveOrder(unitid,c) isn't the issue, but rather IGroupAICallback->UpdateIcons() and CGroup->GetPossibleCommands() As soon as the groupAI passes some possible commands to those functions, Spring will crash upon clearing (deconstructing) the groupAI. | ||||
| Additional Information | I suspect is an GCC issue only, as the 0.72b1 release doesn't suffer from it. This bug appears in CentralBuild, Simpleformation, and MexUpgrader AIs. | ||||
| Tags | No tags attached. | ||||
| Checked infolog.txt for Errors | |||||

I can still confirm this with current SVN (r2531). It is release critical if we consider releasing mingw build. |

traced it down to just after the "delete group;" in CGroupHandler::RemoveGroup (when the crash happens on clicking clear group) or in CGroupHandler::~CGroupHandler (when exiting spring) (ExternalAI/GroupHandler.cpp). Put a log message at end of CGroup::~CGroup (ExternalAI/Group.cpp), and it is executed, put one just after the delete, and it isn't executed. Also it's interesting to note that only clearing the *last* instance of the GroupAI triggers the crash. (If you make two groups with a GroupAI with commands, and clear one, everything is fine. Clear the second, crash.) |
