I cannot post my error log.

I do sometimes get a crash when a battle takes too long (typically when I micromanage too much) and I do attribute it to memory, but that's not unavoidable. If I load my save, I can replay it without crashes. I did notice that EBII is resource-hungry by its size on my disk and its loading times, but that's not a problem for me.

The problem is that the M2 binary could simply fail to allocate memory, and then crash without warning. There's nothing the EB II team can do about this.

Wine doesn't necessarily have anything to do with it this crash. Pretty much any non-trivial application is going to spit out wine-related warnings. Anyway, any difference between Windows behavior and Wine behavior should be reported on the wine bugtracker, though I don't necessarily think this applies.

I don't think memory was the point of my post at all but both you and QuintusSertorius dwell on that point for some reason. Anyway, I'll still try to answer you.
I think it's kingdoms.exe running not medieval2.exe by the way.
I may sometimes get a crash due to memory. Although I'm not a technical person I'm almost sure that the problems I mentioned in this thread are not due to memory and I explained the circumstances of the repeated crash. Because it seems to be solved after I reinstalled everything, I think it was not a bug on the EBII team's part. Also, if there were such a bug, because it is game-breaking, I think it would be noticed and reported much earlier.
Do you mean that Wine is as good as running it on Windows? I didn't think my crash was due to running it on Wine just because the modal window was created by Wine (I'm not THAT unknowledgeable in technical stuff) but because, understandably and as I've heard everybody else say, Wine has its limitations. By the way, one can report application specific Wine issues on this site: https://appdb.winehq.org/ I haven't registered and submitted anything there yet but as I've said, my problem seems to be gone after reinstalling anyway so I don't know (and can't investigate further) what was the cause of my problem now.
