failed asertion

[Ben Sapp]

I am trying to use GiNaC in, GNU Octave, an interactive scripting
language used primarily for numerical analysis.  
Below, I provide some output from octave.   Can you provide any clues as
to what I may be doing to make the following assertion to fail?  What
can I do to fix it?

octave:1> symbols
installing ex type at type-id = 18
installing sym type at type-id = 19
installing vpa type at type-id = 20
octave:2> page_screen_output = 0;
octave:3>  x = sym("x")
x =
 
x
 
octave:4> x^2
octave: basic.h:77: GiNaC::basic::~basic(): Assertion `(!(flags &
status_flags::dynallocated))||(refcount==0)'
failed.
