What did you install just before it all went wrong?

It's a new laptop... I assumed that this was an issue purely with Cygwin or my base OS and not related to either the Windows apps I have or the hardware spec of the system. I agree this is a good place to start though.

  Well, that plus all the references to memory allocation and forking in the
error messages!

Haha - fair enough!

This is the point at which I usually say ...

"  Disable the "Logitech Process Monitor" service associated with your webcam?
Uninstall Agnitum Outpost?  Disable McAffee's buffer overflow protection
feature?  "

I'll start "turning stuff off" and see where I get. I'll report any success back to this group.

Can't think of a witty .sigline today....
