Thank you. As I understand you are using API, not glpsol, because
the mps file contains non-numeric data (inf):

lpx_read_mps: reading problem data from `assert.mps'...
lpx_read_mps: problem name not specified
assert.mps:4224: invalid coefficient value in field 6
MPS file processing error

I think it will be a good idea to check all the problem data within
API routines and prevent passing inf's and nan's to solver routines.
