Fixed a crash in
read_mps_file()when the input MPS file cannot be opened.Previously, if
fast_reader_open(filename)returnedNULL, the function printed an error and continued into the parsing loop, which later calledfast_reader_gets()with aNULLreader, causing a solution on an empty problem.The fix is simply to return
NULLimmediately after the open failure insrc/mps_parser.c.
