Looking a bit for this error message over the net, it boils down to: you need more memory.

In other words, OpenMP runs out of resource, you can either disable it (your workaround), or add more mem to your system. In any case, this is not a Blender bug, and we can't really do anything about it… Thanks for the report anyway.
