Strange that the kernel would make any difference - more likely it's your C 
compiler making the difference.

I ran a test on one machine and got an abort in glibc saying there was a stack 
overrun. On a different machine I got no such error, and running on the 
problem system under valgrind produced no errors.

On the machine that aborted, when I compiled with gcc -fstack-protector-all, 
the glibc abort disappeared as well. So, this hasn't helped me identify the 
problem yet. (gcc 4.8.4-2ubuntu1~14.04)
