bg2: assertion failed in GAMImporter.cpp

[Guest Guest_Chris_*]

Just installed gemrb 0.6.2 on a Debian amd64 stable installation. It seems like it works fine until I try to move my character (i.e. the intro bit in Shadows of Amn plays, Imoen comes to talk to me, and it crashes at the end of the conversation). In Throne of Bhaal, it just crashes as soon as the in game GUI appears. Here is the last few lines of output from gemrb before it falls over:

Any thoughts?

try the git version or wait for about a week for the next release.

This happens when it fails to save the game - you probably have bg2 installed on a read-only partition and you didn't set SavePath in the config? gemrb does have a more helpful error message in the git version, but I guess it's new since 0.6.2.

The git version works. It seems if I copy GAMImporter::PutPCs() from git to 0.6.2 and rebuild, 0.6.2 works as well. Which is odd, because the difference between the two versions seems very insignificant.. The assert in git (around line 1044 in GAMImporter.cpp) uses the CREOffset variable, but the 0.6.2 doesn't (but is passed the same expression that CREOffset is set to anyway) and an extra asset is added before the return line, and it seems that is it. Mind you, given this is the first time I've looked at the code, I have no idea what the assert is actually asserting..

The game is installed on a compressed filesystem (squashfs if you really need to know), but I set SavePath to a normal directory with write permissions.

 

But anyway, the git version is working for me, so problem solved I guess.

It's checking whether the correct amount of data was written to disk - I added them when I found some really nasty bugs which wrote incorrect amounts of data when saving and made corrupted savegames, and wanted to make sure that didn't happen again without it being obvious.

 

Glad to hear it works for you now!

Hearing that just made my day
