Question #93523 on DOLFIN changed:
https://answers.launchpad.net/dolfin/+question/93523
Status: Open => Answered
Anders Logg proposed the following answer:
Looks like a problem in UMFPACK, or the way we call or link to UMFPACK.
Does anyone else get the same problem when running with UMFPACK
instead of PETSc?
You could try enabling PETSc in Dorsal and see if that helps.
