When consolidating all materials into one, including the last material in the list causes iClone to crash.
Consolidating other materials causes unstable behavior.
e.g.
- after consolidating several materials, renaming a material causes iClone to crash.
- iRay can fail to render objects after consolidating materials

This happens in both iClone and Character Creator.

To reproduce:
in iClone, select any character,
import the attached iCloth object (It's a jersey/sweater)
Select the object
Select all materials in the material list.
Click on Consolidate Materials button in the Material tab.
Result:
iClone will crash.

I've attached an iCloth object (jersey2), as well as the original obj mesh created in Clo3D, however this happens with all objects.
