Short description of error
Blender crashes on startup after the interface has loaded. It segfaults on keymap->poll(C) and all keymaps are empty.

Buggy keymaps can result in a crash.
This is something that can improve, but it is not currently considered a bug, unless you can explain how to create a buggy keymap through the Blender interface.

Try to run blender_factory_startup.cmd that is included in the download.

I think you misread the OS : P

Anyway, @Imaginer, I think I heard factory startup wasn't working here.

If you're getting this crash reliably, and you have a bit of time to try to help diagnose the issue, the best think you could do is use git bisect to find the commit that broke things for you. Given the short time range you've already narrowed it down quite a lot that shouldn't take too long.

@HooglyBoogly Yeah, factory startup doesn't change anything. I've been building blender for a while now, because it's been the easiest way to check my addon against the latest master, and everything's been fine, then I started working on a patch for blender and didn't update for a while and the next time I updated master I ran into this issue. Because it takes a long time to compile I've turned off a lot of options in cmake to have a lite build while developing the patch, so this may have something to do with it, but the lite build was working fine before, so I don't know. The crash happens reliably so I'll try doing a git bisect to find the problem commit.

@mano-wii Since I've been developing, I've kept blender in a mostly default state for testing (I've changed a couple preferences like making the addon I develop always enabled and turning off a few things like auto perspective, but hardly anything), so it's not a keymap I created. I just updated to a new master and all the default keymaps were listed as empty. Blender loads fine, I see the splash screen, and then a couple seconds later it segfaults and I see in the terminal this huge list of warnings about empty keymaps. It's very weird.

Anyway, I'll do the git bisect and see what's what.

@Imaginer can you remove your addon to check if it is the source of this problem?

Well, when I went to do the git bisect everything was perfectly fine. There is no sign of the bug at all, and the only commit that I definitively knew that crashed, doesn't crash anymore. I've recompiled it and run it several times and I can't make it crash anymore. So, thank you all for your time and I guess you can close this bug as invalid.
