Hello,
I just ran the auto-adaptive-poisson demo and received the following
output and error. Initially, I received a similar error that suggested
I set "allow_extrapolation" to true. I did this, and now receive this
error. I am running on FEnICS/DOLFIN 1.2.0 and python 2.7.
The error message indicates that you're using the development version of
DOLFIN from the end of November
(https://bitbucket.org/fenics-project/dolfin/commits/088697b95de1dd1d8df17618b0584abbab325b45). There have been a lot of fixes applied to the intersection detection code, so first try updating DOLFIN to the development tip and run again.

Any help
would be much appreciated.
Regards,
Ben
