#17695
The windows exit code is a 32-bit unsigned integer, but the command
interpreter treats it like a signed integer. When a process is killed,
it returns 0xFFFFFFFF (interpreted as -1). We convert the integer to an
signed 32-bit integer to flip it to a -1 to match our expectations, and
fit in our db column.
