There is a common rule: the alginment boundary for a data type X cannot be more than a multiple of sizeof(X) (it is assumed that sizeof(X) = 2^n). Otherwise, an array of type X would need to have "holes" that contradicts to definition of sizeof(X). In glpk the size of all basic data types are not greater than 8 bytes, that's why I do not understand where the alignment error may happen. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
