  Won't work. The problem is startup options like -malloc are processed by PetscInitalize(). Since you set it after PetscInitialize() it won't have any affect. You need either on the command line, in the environmental variable PETSC_OPTIONS or in a file .petscrc either in your home directory or in the working directory.
