System Information
Windows 8.1 x64
Intel i5, GTX 560, 8GB RAM

Blender Version
2.69.0 (r60995) and 2.69 (b096845)

sorry for my English, I use Google translator.
I created object and added modifier Subdivision Surfatse, applied it.
With the aid of The Boolean modifier and cylinders cut out holes.
The Boolean modifier applied.
I got an object with holes (in blend file)
Now when I go into edit mode and select a vertex or edge, it's okay. But, when I select the polygons, Blender freezes.

Confirmed on linux x_64. In fact, it's even worse for me. If I open the blend file, go into edit mode and click on the icon that sets selection for face mode, blender already hangs
at exactly 100% cpu usage (it is maxing out one core, but not using others). A kill command from the console is required to shut blender down.

However, if I make a simple cube and intersect it with a cylinder, I don't have the problem. So there is something specific in the blend file that triggers this.

Yes, many times I use Boolean operations, but this happens for the first time

Opening the file and going into edit mode fails on bmesh assert:
https://developer.blender.org/diffusion/B/browse/master/source/blender/bmesh/intern/bmesh_core.c;b5aef37c27f5fb2a4bb4227253f81d886ddd796c$557

If i disable ASSERT_ABORT i can reproduce the freezing as well, it just gives lots of assert messages on stderr then.

I couldn't reproduce the faulty mesh by making my own boolean modifier and applying in recent Blender version. Could you please try repeating this procedure on a recent build from builder.blender.org (re-doing the boolean modifier and apply, not just opening the broken file).

@Sergey: I assume this is a problem with the recent boolean changes, so assigning to you. It may have been fixed since the mentioned build (14th february).

Couple of things:

Boolean integration is fully rewritten now, so please give it a try with latest builds from http://builder.blender.org/download/
It's not possible to do anything with your file actually. it's totally lost now.. We do need .blend file before you hit any "Apply" on the boolean modifier. This way we can check where exactly mesh became corrupted.

So please try reproducing the issue from scratch using latest builds and let us know whether bug still happens (n this case provide .blend file at the stage boolean modifier is not applied yet). Or likely blender will just work for you.
