Just to add a data point in case somebody wants to look at this:
Looks like a smashed stack: gdb'ing drops you dead in libc's _start() when
you get back from the "call main", if you use "exit" instead of "return" in
main, something else goes wrong...Interestingly, the problem goes away when
linking with ElectricFence.
      

Interesting, you're able to reproduce this?  I couldn't even do that
outside of bento.
    

In fact, I think I just nailed it:

The port uses threads, and you'll see many incarnations of
"cc .. -pthread -lc" which really strain the eyes.
Stripping the "-lc" from the configure-script seems to do the trick.

I'll submit a patch once I cleaned up.
