Destroy unwind address space
#include <libunwind.h>
void unw_destroy_addr_space(unw_addr_space_t as);
The unw_destroy_addr_space() routine destroys the address space specified by argument as and thereby releases all associated resources (such as memory).
Applications must not destroy the local address space unw_local_addr_space. Attempting to do so results in undefined behavior (e.g., the application may crash).
