--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
OpenSSL of course.  136 << 24 is not representable in int.
This is undefined behavior in C99/C11, and defined behavior in C++11.
Quoting C99 6.5.7/4:
"The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are
filled with zeros. If E1 has an unsigned type, the value of the result is E1 ×
2 ^ E2, reduced modulo one more than the maximum value representable in the
result type. If E1 has a signed type and nonnegative value, and E1 × 2 ^ E2 is
representable in the result type, then that is the resulting value; otherwise,
the behavior is undefined."
