Thank you for your bug report. Unfortunately, I'm unable to reproduce the effect due to a regex error: mao@corvax:~/Desktop/glpk$ make g++ -Wall -Wextra -pedantic -O3 -g -march=native -std=c++11 -c glpk.cc -o glpk.o g++ glpk.o -lglpk -lm -o glpk mao@corvax:~/Desktop/glpk$ ls glpk glpk.cc glpk_matrix.txt glpk.o Makefile mao@corvax:~/Desktop/glpk$ ./glpk terminate called after throwing an instance of 'std::regex_error' what(): regex_error Aborted Please write the instance to a text file in lp format (with glp_write_lp) or better in glp format (with glp_write_prob) and post it either to the bug-glpk list or to me.
