GCC 6 now warns

../libinterp/octave-value/ov-oncleanup.cc: In destructor 'virtual octave_oncleanup::~octave_oncleanup()':
../libinterp/octave-value/ov-oncleanup.cc:92:7: warning: throw will always call terminate() [-Wterminate]
../libinterp/octave-value/ov-oncleanup.cc:92:7: note: in C++11 destructors default to noexcept

and an error in an onCleanup function can trigger this problem.  The following is sufficient to demonstrate the bug:

function foo ()
  onCleanup (@() error ('oops!'));

A possible fix is attached.

Maybe we should also display the message from the last error along with the new warning about an error in the cleanup function?

What does Matlab do for something like this?
