I run Mountain Lion, a fresh install, brand new Macbook Pro. HD: Samsung 840 Pro 512 GB SSD.

When trying to go through Boot Camp Assistant / Setup it works fine until it wants to repartition my drive. It then quits unexpectedly and returns these errors: 

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x000000000000003c

Everything else on this new machine works like a charm. I checked permissions, verified the disk - no issues whatsoever.

I tried running the Assistant as root - it also crashes when partitioning but then in the Terminal i get a 

Segmentation fault: 11

Can anyone help me out with this?

I have not been able to solve the issue, but i was able to find a full workaround. As Boot Camp Assistant crashes AFTER it creates the USB drive with the BC drivers for Windows, i just partitioned the harddisk again myself (in Disk Utility) and then booted up manually and normally with the Windows 7 CD, installed Windows 7 on the target partition and then installed the BC drivers from the USB drive. Everything works perfectly well. – Cummander Checkov Feb 5 at 10:12
Great you could find a workaround. I'd suggest that you answer your own question describing the workaround as you've done in the comment and mark the answer as accepted. – jaume Feb 5 at 10:49

I just found a solution that might work for you... Unplug all the external devices that you might have (external disks, flash drives) and then start the bootcamp again.. I just did it and it worked fine for me!!! :)
