--- Comment #3 from Ian Lance Taylor <ian at airs dot com> ---
Yes, the intended use is certainly to create the state once per program.  Each
time you create a new state and use it for a backtrace the code does a bunch of
initialization work reading the debug info.  Much better to do that only once. 
Plus there is the memory leak problem.

That said, yes, there should be a function to free a state.  But this code
should really change to create the state once anyhow, if at all possible.
