If I were going to devote my time to such a task, and let me be clear that I have absolutely no plans to do so (I prefer and have always preferred Age of Empires 2 over StarCraft so I don't have quite a deep affection for the game as most others here), then I wouldn't be able to guarantee support for Olly because I wouldn't be using it - I'd be using WinDbg instead.
The first thing I would look for if it were me is the crash dump. What was the error code? In what process / memory space (the executable or one of its DLLs?) did the error occur?
Hint/Speculation: the problem is probably located in Battle.snp, assuming that library still contains the code for the game's interface to Battle.net.
