No.  Look at the code.  For R_PPC_REL24, delta is shifted by 6 bits left
and right and should stay the same.  It's a 32-bit signed integer.  The
overflow would happen for positive numbers that exceed (0x7fffffff>>6)
or 0x01ffffff.  A similar limit exists for negative numbers.  I suggest
that you add some print statements to find out what's happening.
