Think of x == y == 0x10001, x * y == 0x100020001, which is 0x20001 in 32bit world. This can still result in small buffer that may be overflown later. The test is usually written as: y != 0 && x > (TYPE)_MAX / y (first part is needed if y can be 0, not needed in cases where y is sizeof(sometype)). -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Fedora-ocaml-list mailing list Fedora-ocaml-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-ocaml-list
