You can't put -skip_petscrc in the code specific file.  The whole idea of -skip_petscrc is that it keeps the code from trying to open a file.  The code opens the code specific file first, then command line args, then checks for -skip_petscrc.  So you need to give NULL for the the "file" here and put -skip_petscrc on the command line, if I am reading the code correctly.
