Vikram ran into some as-yet-unidentified problem with the new L2 option for PatchRecovery last week, but that's almost certainly unrelated. There's a bug in our libHilbert interface that could have corrupted an old output file; that's why for now we disable libHilbert by default. Assuming you're trying to restart from newly generated output files, would you make sure LIBMESH_HAVE_LIBHILBERT is commented out in libmesh_config.h, please? Is this the first error you hit in dbg mode? If not then knowing what assert first fails might help. If so, then could you run though -start_in_debugger and give us a stack trace?
