I finally got around to looking at the link you provided about error 0xC0000409, and realized that I'd been completely confusing it with stack overflow --- but actually, it's a report that something scribbled past the end of a finite-size local-variable array. So I now think that Matthew's stumbled across two completely independent bugs, and we've fixed only one of them. The 0xC0000409 error is something else, and possibly a lot worse since it could conceivably be a security issue.
It still seems likely that the actual location of the bug is either in PostGIS or in the GIST index code, but without the ability to reproduce the failure it's awfully hard to find it. Matthew, could you try a bit harder to find a self-contained test case that produces that error?

Sure, it might take me a while to find time but I'll keep it on my list.
