I don't know why Blender is crashing, but it is crashing a lot. Crashes seem to be related to running the game engine (but not exclusively). And then crashes seem to occur more often when I exit the engine with the ESC key.
That's not much to go on, I know, and the .blend I'm using is not at all simple and a bit of a mess to upload. So I went researching post-mortem debuggers, and had success with Microsoft's ADplus. Now I have a "log and memory dump" folder, and I have no idea what the information in it means. I've attached the log, report and debuggerscript. I don't know if this is useful at all.
Is this sort of thing helpful? Is it useful to submit these logs/reports?
And PLEASE - how do I stop getting an email of every single Blender 2.5 bug submission and reply????

@John, I had a look at this info and still cant tell what this bug is about (suspect its because this is not from a debug blender build) - some options.
* Build a debug blender build and get more info.
- http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Windows
* Test on other systems, try figure out if its related to you're configuration drivers
* Switch windows to a Vesa graphics driver (which uses software OpenGL and may expose if this is a graphics driver bug)
* Test different builds on: www.graphicall.org, perhaps this is a build issue? - Im sure we'd here more about this if it was a common problem.
Re: Many Emails - theres a "Monitor" link you need to disable to stop getting mails.

Apologies, I didn't even put my system specs down - I'm running Win7 x64, and a build off the blender build bot (r40919). ATI 4850 graphics card.
You're correct, the build is not a blender debug, the files are created with Microsoft's ADPlus. Which I gather from your response doesn't provide any helpful information.
I've never built Blender, or anything for that matter, so step one is out for now. I might try it.
I will try the second, third, and fourth suggestions - we'll see if I can figure out where to get ATI vesa drivers.
Vesa drivers come with windows and are generic which is why they have no hardware acceleration, you dont need to download them, (at least with XP they are included).
First I should say that, out of curiosity, I got the most recent 32bit Win build (r40892) from the build bot. That has produced no crashes. This must be an 64bit issue?
Other builds: I tested the .blend with other recent Win x64 builds off graphicall - they do crash.
Other systems: on Ubuntu 11.04 32bit, there were no crashes (tested for about 5 minutes - it crashes within 1-2 minutes on Win7 x64)
Vesa drivers: I uninstalled my video card and tried the file with no drivers installed - the file did not crash.
I actually tried building a debug Blender (following the wiki directions) but I just could not get a functioning one built.
So, my last effort is to upload the file. It's ~40MB, and only missing the video textures that wouldn't pack. But those scenes that use the video texture are not where it crashes - it has only crashed in the scene "hut interior".
Oops - can't upload more than 5mb. Well, here's the dropbox link, it will take some time to upload. http://dl.dropbox.com/u/13175083/ScottsHut10_10_11_packed.blend
(And, keep in mind, this is very much a work in progress - and my first Blender game project, at that.)
--- "Vesa drivers: I uninstalled my video card and tried the file with no drivers installed - the file did not crash."
This seems to show the bug in not in blender but in the graphics drivers on 64bit windows. - not sure there is anything we can do to fix in this case.
I'm sure I'll show my ignorance of how all this works with this question, but wouldn't 32bit Blender running on a 64bit OS still use the system's 64bit graphics drivers? (I have got 32bit blender to run the file without crashes.)
Think this can be learned using Help -> System Info and checking which video card/driver is used.
@ Sergey - Blender tells me: "System information generated in: 'system-info.txt'" Where is this file generated? I've generated it multiple times and searched the entire hard drive, but there is no file by that name.
For what it's worth:
Video card/driver is same for both 32bit and 64bit versions of blender (2.60a)
renderer: ATI Radeon HD 4800 Series
vendor: ATI Technologies Inc.
version: 3.3.10750 Compatibility Profile Context
The only difference between the two system-info texts (besides build cflags) is Python 32bit vs 64bit.
I should also mention I'm running both 32- and 64-bit in their own folders (not installed) on the desktop - meaning Blender 32bit is not running from inside Program Files (x86).
