RepFix is a BWL/ChaosLauncher plugin which fixes StarCraft's (1.16.1) crash when watching a replay with chat text recorded while game was paused.
Download v. 0.0.0.4: http://depositfiles.com/files/wk71bm2ie
The bug itself seems to be very old.
Basically replay action processing looks like:
1) read the actions for next tick and copy actions data to the buffer
2) wait until that tick comes, read actions from the buffer and execute
When game is paused the tick remains unchanged, so every chat message written while game paused has been recorded with that tick when game was paused.
The problem is in that the buffer in which actions are copied for execution is too small. I believe about 12 messages are enough to make it overflow. And when overflow happens the data overrides neighbor memory areas in which are other variables located.The consequences can be very different and depend on amount of messages has been recorded during pause.
What I did is a replacement of static buffer with dynamic one.
1) when copying actions to the buffer:
1.1) when overwrite - allocate new buffer, write data to the new buffer
1.2) when append (multiple actions for a single tick) - append to the previously allocated buffer increasing its size if needed
2) when reading from a static buffer - return a pointer to the dynamic buffer instead of static
Plugin patches StarCraft's code, so use it on your own risk!
I will be very appreciated for any testing/bugreports.
Later I will merge this fix into ICCup Launcher.
EDIT: It has nothing to do with saving a replay, it just fixes a playback
You need this only when watching a replay not playing a game.
Thanks.
PS: I believe the main mistake of BW developers was to count chat text as game action. I would rather record/read it in a different way. But I'm not the one who decide ^^
EDIT: http://www.iccup.com/starcraft/forum/general_forum/starcraft_forum_/50888.html?1232900679
EDIT2: the bug is old, but it was impossible to produce so many actions for a single tick... before RWT was implemented! Because player was unable to make game actions while game paused. Thats why I believe that text messages should not count as game actions.
UPDATE: v. 0.0.0.2 should work online now.
UPDATE: v. 0.0.0.3 fixed action loss in bnet-mode.
UPDATE: v. 0.0.0.4 fixed activation behavior (when replay starts)

nice 
Starcraft had(I think it was fixed in 1.15.0) a bug where if the data for a replayframe was >255 bytes the replay got corruped. In that patch they corrected it to start a new replayframe with the same framenumber containing the remaining commands which apparently fixed the problem(PP did it way before blizzard by the way). So I'm surprised that chat cause these problems, while multicommands do not. They generate many commands in one frame and corrupted the replay before the fix.

I loaded this into Chaoslauncher.
When I am trying to connect to Battle.net (Europe) with English StarcraftI get an error saying that Starcraft can't verify the application version. A friend of mine has the same problem.

Each message action is 82 bytes long. I think such amount of data (per tick) as 12-15 messages was not reached yet, until RWT xD

OMG, I just patch it when started, but seems I should wait until replay starts then patch...

Very nice job, Python But yeah, try to make it wait til a replay is loaded
Offsets I use for that:
006D0F14 - byte, 0 for out of, 1 for in replay
006D11EC - byte, 0 for out of game, 1 for ingame
(You have to use them both, because the replay one will for some reason trigger when you first enter the menu to load a replay (the file selection part). Actually, now that I think about it, using only the first one would probably work fine for this application)

i don't think you can use this online cause he modded the code of starcraft...

no it's just that he patches to early and thus fails the revision check. He just needs to patch only during a replay. But of course anybody without this fix who watches the replay with you will still crash.

at least it might speed up Blizz's patch  ...
+ Show Spoiler +might take a month and 1/2 instead of two

You can't use this fix online, but it's still nice to have for offline use.
