Title: CRC mismatch on 3.10-dev-git4702.51f4b6d
Post by: tomreyn on 31 January 2014, 23:46:25

Coldfusionstorm (Windows 7, always client) and I (atibox, always host) were testing game state CRCs (EnableNetworkGameSynchMonitor=1) today.

First we tried git head. Coldfusionstorm ran into a mismatch during the first attack.
linux host: http://tomreyn.megaglest.org/debugCRCWorld_tomreyn_2014-01-31_1.tar.gz (http://tomreyn.megaglest.org/debugCRCWorld_tomreyn_2014-01-31_1.tar.gz)
windows 7 client: http://www.megafileupload.com/en/file/495172/debugCRCWorld-7z.html (http://www.megafileupload.com/en/file/495172/debugCRCWorld-7z.html)

Then we tried 3.9.1 (32-bit build on Windows) - no problems at all.

Then we tried 3.9.1 (64-bit build on Windows), and, after 10-15 minutes of gameplay, Coldfusionstorm ran into a CRC mismatch:

I have re-enabled streflop and added win64 support to the library (And win64 build). This should make it more stable again, please try the latest git.

Thanks, how do we build Windows 64-bit builds then? Is it the default now? On Windows build's --version output, it only says "Windows" for platform, so I don't know whether that's 32 or 64 bits.

We did a test game today with 4704.78ed6d4 (everyone did a full rebuild, host and all clients where reporting this same revision). We had mixed platform teams:

tomreyn (on Linux 64-bit, hosting) + Jammy (Windows 7 64-bit with 32-bit build)
vs.
Filux (Linux 64-bit) + Coldfusionstorm (Windows 7 64-bit with 32-bit build)

What happened is that while the first team was attacking, both players on the second team simultaneously ran into a CRC mismatch (both clients) and disconnected. However, the first team remained connected.

So this my be a false positive, since it happens on mixed platforms?
