Redis A runtime error caused by invalid-shift-base in source code

Source code： hash = hash ^ (hash >> 24);

ISO standard： 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.

@WLLS253 can you please specify what generated that report? i.e. as far as i can tell that's not a redis crash report.. also, what OS / platform / toolchain are you using?
