%%%Blender on WinXP 32 Bit, Radeon HD4870

When intersecting a cylinder with a sphere, blender 2.61 crashes, latest build (r43944) files an Error (the report to MIcrosoft question), details s. attached picture. To provoke crash: execute python script and set divs >=74. For divs <74 it works for me, in blender 2.61 it produces wrong ouput until divs=80.

Cylinder with rounded endplate

import bpy
divs=81

bpy.ops.mesh.primitive_cylinder_add(vertices=divs,radius=5.3,depth=3.0,location=(0.0,0.0,0.0))
bpy.ops.mesh.primitive_uv_sphere_add(segments=divs, ring_count=divs, size=69, location=(0.0, 0.0, 67.5))

cy=bpy.data.objects["Cylinder"];
sp=bpy.data.objects["Sphere"];

bpy.context.scene.objects.active=cy
bpy.ops.object.modifier_add(type='BOOLEAN')
cy.modifiers- [x].operation='INTERSECT'
cy.modifiers- [x].object=sp
bpy.ops.object.modifier_apply(apply_as='DATA',modifier='Boolean')

bpy.context.scene.objects.active=sp
bpy.ops.object.delete()

%%%Issue is caused by duplicated vert in UV sphere which shouldn't happen. Corrected sphere creation in rev43983. It's not actually a bugfix but will resolve possible stoppers.
Anothert this which will he here a lot -- move sphere a bit to the bottom (i.e. by -0.01 in Z direction). It will allow to produce a bit better topology on result.

I've informed Tobias (Carve library developer) so he'll look into this issues, so workaround with moving sphere and duplicated vertices wouldn't be needed.%%%

%%%I tested with 44001 from builder.blender.org and it now works fine for my script. Thank you%%%

%%%Found in blender-2.62-r45731-win32 (and earlier official 2.62 builds) in WinXP

Trying to append a 2.61 scene in 2.62 resulted in a crash, so I dissected the scene and found which object led to the crash. Since it involves a boolean modifier, I'm assuming that it is related to this bug.

I marked one spot that seems to cause the crash - straightening that part prevents the crash in 2.62, but at the same time, the intersected part becomes invisible !
If I delete the other part of the mesh that is not connected to the intersected part, the crash is gone as well and everything is visible like it should.

I've attached the file so you can check if it is the same bug. I would hope that this can be fixed before 2.63 so I can import my files again.%%%

%%%Hello, in the latest build (46804), the boolean modifier crashes blender, everytime and with all methods (intersect, union and difference).
.blend files using boolean modifier cannot be opened because of this bug.
Keep the courage.
