Essentially, this failure boils down to: when generating the array of uniques for booleans, we pack 8 bytes at a time into one byte. The bytes are packed from what turns out to be a scratch array allocated by TempVectorStack, which does not initialize its memory. So we may end up packing initialized bytes and uninitialized bytes together into a single garbage byte, resulting in Valgrind complaining. -- This is an automated message from the Apache Git Service.
