System Information
Windows 7 Professional x64
Nvidia GeForce GTX 780 x2

Blender Version
Broken: Blender 2.71 Hash: 9337574

Short description of error
Using a Boolean modifier, when it is using the operator of difference of another object, then hits render, and when it's processing the object that has the boolean modifier, MOST of the time it crashes, also when hiting "Display modifier in realtime" button (that has an eye on it), happens also most of the time.

Exact steps for others to reproduce the error
Using a Boolean modifier below a solidify modifier of a simple plane (4 vertices), using in the boolean a operator of difference, using another object that is partially inside of the object, the object that is partially inside is a mesh separed in various parts (in my case they are lamps) that conforms the entire object.

Example Blend: prueba_bug.blend

The error exists, the crash disappears when is removed the modifier subdivision of the "lamparas_techo".

I have examined the example Blend file. It does crash on my system when rendered...

BUT...

I note each of the sub object groups of the mesh object 'lamparas_techo' has a non-manifold outer shell.

In my understanding of it, the boolean modifier is designed to work with manifold objects.

The boolean modifier will sometimes work with a non-manifold object, but in general this is very bad practice and leads to instabilities.

I think one of the programmers could make a more informed comment on this.

Boolean modifier does not handle non-manifold cases very well… But it should not crash! Sergey, sounds for you. :)

As I remember the scene that I was working with this two objects worked well in 2.69, but when I took the file again with 2.71 and 2.70, this happened... Hope it helps :)

For what’s worth, here is a bt, segfault happens in Carve :/
