Can you reproduce the crash in a new scene or does it only happen in this file?

Which version of Blender are you using exactly (the hash on the splash screen)?

Currently I can't reproduce a crash.

hm..i cant reproduce too..
hash 4c31bed6b4

ok - include the scene-i find the way to reproduce.
open scene, open shading tab, select (if not yet) wall, in bottom node editor try to change material like in this screenshot https://yadi.sk/i/j-7WKUVIw268RQ
after that - boom! crashed! everytime.

The Blender version you are using is already more than two weeks old. Please check if the bug still happens in the newest version.

The issue seems to be with material preview "rendering" the preview_sphere object (from the preview .blend) and trying to use a material that is trying to use a UV that is not there.
That leads to the following assert:

BLI_assert failed: //source/blender/draw/intern/draw_cache_impl_mesh.c:1031, mesh_render_data_create_ex(), at 'CustomData_number_of_layers(&rdata->cd.output.ldata, CD_TANGENT) == rdata->cd.layers.tangent_len'
Full backtrace: P876

(For the records, early on I get a warning which may be related):
//blender/intern/mikktspace/mikktspace.c:1524:21: runtime error: shift exponent 32 is too large for 32-bit type 'unsigned int'

There are multiple ways of reproducing this. For example:
material_preview_bug.blend

Just open this file and rename the UV in the mesh panel.
