You are right, pid_t is __int32_t, which is signed, so "%d"
is the correct format.

I assumed that in this case, the signed integer overflowed,
so maybe interpreting it as an unsigned integer would make
more sense.

However, I don't know what could cause a pid_t to become that
large. On 5.x, fork1() tries to find an unused pid for a new
process and checks if it lies between 100 and PID_MAX.

Cheers,
Toni
