Details:

Dear octave developers,

with a wrong signature in an overloaded 'subsasgn' operator, octave stops with
an segmentation fault.

In this case, I left away the return value. See appended tar.

I took the newest octave source and even here, the bug remains and it
appears:

Program received signal SIGSEGV, Segmentation fault.
octave_user_function::subsasgn_optimization_ok (this=0xbc4c50) at
octave-value/ov-usr-fcn.cc:658
658           && ret_list->length () == 1 && ! ret_list->takes_varargs ())


This bug appears also in my older 3.6 release.

Best regards
  Thorsten Gellermann
