Tested this, it seems to me it has to do with the 'margin' bake setting.
I´ve had this prob yesterday (r54289) while baking image texxtures + geometry to normal map from hipoly mesh to lowpoly.mesh.
Highpoly : duplicated mesh w. 1x subdiv. + applied subdiv modifier.
Bake setting: clear, selected to active, margin 2, mode normals / tangent, split automatic.
There are grid-based artifacts on the bake. Seems to me it presents the mesh grid from the lowpoly mesh into the bake.
Margin 2 or higher - artifacts present
Change margin to 1 - artifacts are gone
Change margin to 0 - blender. crash to desktop
I can reproduce that error with r54336 with my blend and with the attached file from *kromar above.
- winXP
- core i7 2700k
- nvidia gtx 460
- ram 4 GB (3,5)
tested with:
r54336
r54289

re-opening, though it sounds as if the error your talking about is a totally separate bug.

Ralf, does crash happen with RC build from http://download.blender.org/release/Blender2.66/ ?
Also, could you please attach file which crashes for you? It could be some setting different in your default scene or so which affects n crash..

No reply in quite a while. Wasn't able to reproduce the issue and there were some fixes related on margin and baking since that time.
If someone still have got issues with baking, please leave a reply here and attach file which demonstrates the issue.
