%%%Could you please attach a blend file that demonstrates this problem, or provide clear steps to reproduce the problem?%%%

%%%Just save the standard cube scene with an new Blender version.
Then open and close it with the player. On close Blender will crash.

I have uploaded also two blend files now.%%%

%%%I can confirm the crash also.
ive been aware of the crash for awhile but couldn't seem to narrow it down very well so didn't post it here.

But ill also add as it seems it stems from the same problem, that even if the blend file is saved with 2.67b official and its opened in a newer revision of blenderplayer such as r57570 it will still crash on exit when a new blend file is loaded from within the game engine even though all the blends were saved in r57141.%%%

%%%Should be fixed in r57680. Can you please confirm that this fixes the problem for you?%%%

%%%This fix has sadly made it worse it does now however not crash on exit when loading the first blend into the blenderplayer however it will crash every time now when exiting on the second blend wasn't happening before, and will now crash every time on loading a third blend file using the game actuator in blenderplayer.

I tested with a buildbot build rev blender-2.67-r57690M-win32
I made three blend files with this revision to test and will upload the three blends here.

To reproduce the crashes open blend1 in blenderplayer r57590m hit spacebar to load blend2 up, exiting should cause a crash on exit.
And then to reproduce crash two hit spacebar twice to load up blend3 and it should then crash on load.
It crashes every time for me on windows 8 where as before it was less persistent with previous versions and non existent with blender 2.67b official

I will upload the three blends in a zip file here if it lets me%%%

%%%Your patch fixed the crash with closing the blenderplayer.
But as James Press mentioned there is second bug that I didn't know.

I have seen that in blender.c there is also a free_nodesystem() function. But it seams that it don't work in blender.c
If I remove the free_nodesystem() from GPG_ghost.cpp and blender.c Blender not crash but I get much more memory leaks.

I think this is related with the other bug, therefore I don't open an new bug report.

I uploaded an example file.%%%

%%%I think I found a proper solution for both issues.
You need to place free_nodesystem() somewhere after the while loop and before RNA_exit().

I added the patch.%%%

%%%Please try r57711. Loading multiple blend files caused free_nodesystem() to be called multiple times, which the function was not expecting.%%%

%%%I can confirm crashes fixed with r57711. well played!

confirmed with build r57724. crash on exit no longer occurring, and crash when loading a blend file with the game actuator no longer occurring.%%%
