Several compilers such as clang/icc/pathscale will optimize the check pos + size < pos (assuming size > 0) into false, since signed integer overflow is undefined behavior in C. This breaks overflow checking. Use a safe precondition check instead. Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
