Incompatible battle replays across OSes

Another wild thought here. If you recompile Dom2 with different byte alignment and try to compare if the battle replay goes the same way in the old executable and the new one (on the same machine). If they're not going identically, surely there must be some uninitialized variables or memory overruns.

I have just installed and tried 'valgrind'. Seems like an excellent program to find variable that are used unitialized. Let's just hope it finds something interesting.

We also experienced inaccurate battle replays. In fact the battle replays have absolutely nothing to do with the battle report.

We're playing a 2-player MP game with a Linux host and 2 Windows clients.

I hope you can find that bug. It's not really *that* important but the battle replay is really helpful for tweaking the army setup/spells. Especially for us newbies...

Methinks that the totally inconsistent replays observed by PhilD rather show some problem/bug with the replay module itself than some n-th precision difference in the combat algorithm between various C++ compilers...

We experimented a little bit more and don't have problems when hosting and playing on windows. I'm almost certain that this is a cross platform issue.

How do you people understand this stuff?

It's technomancy. If you don't understand what any of it means, you're probably not going to unless you take up computer programming. Try researching the Technomancy school. This should make sense to you once you reach level 6 Technomancy or so.

Also, didn't this thread die ages ago? I recall the causes of the battle replay incompatibility was caused by differences in order of execution in the MR if() check?
