Function 'do_mapply' in mapply.c has the following fragment.
for (int i = 0; i < longest; i++) {Variable 'longest' is declared as R_xlen_t. Its value can be larger than the maximum int. In the fragment, when 'longest' is larger than the maximum int, when 'i' reaches the maximum int, i++ will lead to overflow. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
