I will change the Subject line "execve exit status on MIPS" first.

My intenstion is not to overflow in string...
We can change

to
     strcpy(e2BIG[ind], "helloworl");

But intenstion is to generate E2BIG in
  if ((ret = execve(EXE_NAME,e2BIG,envList)) == -1) {

where e2BIG array has more number arguments than ARG_MAX.

Which was possible on ARM,PPC and i386....

For the same code...I got 14 EFAULT....


Thanks,
