Hi,

I am trying to use ptrace for a particular case where I want to skip
the instruction pointed to by eip. I am using PTRACE_SINGLESTEP as the
request to get to the instruction I want to skip.

When I get to that particular instruction, I do:

data.eip += 2; //since its a 2 byte instruction
if ((error = ptrace(PTRACE_SETREGS, pid, 0, &data))) {
perror("SetRegs:");
break;
}

But this somehow does not work :(. My program goes in some wierd
infinite loop. I am on a 2.6.9-39 kernel and dont have PTRACE_SYSEMU.

Help appreciated.

-Shri
