I encoundered an access violation with the unmodified sources from SVN in Universe::StoreTargetsAndCausesOfEffectsGroups, universe.cpp around line 997 (the iteration over effects_groups). The relevant call to this function is in Universe::GetEffectsAndTargets, same file around line 953 (iteration over buildings). The exeption gets thrown in the second iteration of this loop in my build. For some reason the debugger don't want to show me the contents of buildings (undeclared symbol).
It seems like the first passed parameter to StoreTargetsAndCausesOfEffectsGroups (effects_groups) is invalid. The debugger shows '[...]()' for its value and I've no idea what that's supposed to mean. An empty std::vector would appear as [0]().
Maybe it has to do with a recent change in buildings.txt, where the effects for BLD_SHIPYARD_BASE and BLD_SHIPYARD_ORBITAL_DRYDOCK have been removed, but even when I reverted this change the exception was still thrown.

With an ugly try { ... } catch { return; } I was able to suppress this error and ingame it seemed to be just fine, but this is certainly not the preferred way to fix this.

Can someone reproduce this error?

btw: is there an easier way to attach the debugger to the server before universe generation than hosting a multiplayergame and then joining with a second local client? Somewhere I read about a --force-external-server option, but it seems as if it has been removed.

Consistently, or just once? With any particular galaxy setup options or with any? Does it happen with the v0.3.13 release as well? Immediately after starting a new single-player game when running the program, or only after resigning a game and starting another, or only when starting a multiplayer game?


Add debug output to console or log file. To do this, iterate through whatever container you're interested in and output something relevant about its contents:



Is there a little + button? If there's a bunch of stuff in a container, the MSVC debugger sometimes lets you expand the container. If it's gotted confused and can't evaluate the container properly, it sometimes says it has 500000 entries in it, or somesuch, though.


It's more likely related to the one before that: http://freeorion.svn.sourceforge.net/vi ... ision=3041 in which building effects were made optional.


Possibly, if you can be more specific (see above).


When on the single player galaxy setup screen, the server has already been launched and can be connected with the MSVS debugger.

This happens consistently. I tried all available galaxy shapes, various variations of age planet density etc. and multiple numbers of AIs (including none).
It doesn't happen with the release build though.



No, there isn't. Actually it would be surprising, because all other calls to this function before the one causing the exception pass a vector of size 1.

I'm currently fiddling with some debug output and post here if I find something more significant.

I just run svn up, rebuilt the whole project and the error disappeared. I decided to treat it as a cosmic ray.
Thanks for your help anyway.
