Ian Lance Taylor <ian at airs dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ian at airs dot com --- Comment #1 from Ian Lance Taylor <ian at airs dot com> --- Programs are expected to call backtrace_create_state once. There's no reason to call it more than once. Yes, I agree that it would be nice to have backtrace_free_state, but it's hard to write correctly. And it's hard to see why any program would want to call it, as it would be less efficient.
