Which demo is it, and are you sure it is a PETSc related error? I have one python demo that still fails on me. It is function/projection-interpolation When PETSc is the linear backen PETSc debug messages kicks in, but when uBLAS is the backend I get a "normal" stack trace. The segfault only appears when DOLFIN_NOPLOTS is defined, so it is a strange bug, and seems to occur when the memory is released. Here is the full output when failing: Checking mesh ordering (finished). Assembling matrix over cells (finished). Assembling vector over cells (finished). Solving linear system of size 36 x 36 (uBLAS Krylov solver). *** Warning: Conjugate-gradient method not programmed for uBLASKrylovSolver. Using GMRES. Krylov solver converged in 7 iterations.
