Details:

I'm not sure if this is supposed to work if Octave isn't installed. But if I
run the following in Octave that I started with `./run-octave --g` after
compiling inside `.build` in the source tree, the executable dumps core:

>> mkoctfile ../examples/code/embedded.cc --link-stand-alone -o embedded
>> system('./embedded')
GCD of [10, 15] is 5
*** stack smashing detected ***: terminated
Aborted (core dumped)
ans = 134


With gdb, I see the following:

(gdb) r
