It is neither a bug nor limitation. I think that the problem can be resolved by increasing the stack size, say, to 1 or 2Mb; you just need to add corresponding option in the makefile (see CFLAGS variable). _______________________________________________ Bug-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-glpk
