I've been happily building on Ubuntu Karmic from Mozilla-Central trunk
for months. But now building fails in some Python step or other. Just in
the past 24 hours.

Is anyone seeing similar?

Thanks, Martin

and then it ends back at the command prompt.

A circumvention turned out to be to turn off optimization in PLY in the
routine that line 2718 in yacc.py is in.

I did it with a optimize=0 inline in the code. I'm sure that's the wrong
way to do it and doesn't fix the underlying problem. But it got me going
again.
