Log Message:
Disallow resuming program with PC=0x0 in ptrace(2)
If the address parameter is 0, report error.
It's a popular mistake to set Program Counter to 0x0.
In certain kernels this is allowable parameter and causes
portability issue.
Disallow explicitly zeroed PC, instead of triggering
a harder to debug crash later.
