[Help-glpk] counteracting infinite loops

[zephod]

I'm using GLPK version:

#define GLP_MAJOR_VERSION 4

#define GLP_MINOR_VERSION  60

For one of the inputs (out of many thousands that I'm running) the simplex solver goes into an infinite loop. I include part of the output below. My question is: is there any flag I could set for GLPK to abandon this computation after enough unsuccessful steps or something else that I could do to counteract infinite loops.
