Thank you for your bug report.
Unfortunately, I'm unable to reproduce the effect due to a regex error:
address@hidden:~/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
address@hidden:~/Desktop/glpk$ ls
glpk glpk.cc glpk_matrix.txt glpk.o Makefile
address@hidden:~/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. Thanks.
