To test whether _M_get_thread_id/_M_initialize/_M_destroy_thread_key works I was using following testcase under debugger: #include <pthread.h> #include <unistd.h> #include <memory> #include <ext/mt_allocator.h> using __gnu_cxx::__pool; using __gnu_cxx::__common_pool_policy; using __gnu_cxx::__per_type_pool_policy; typedef __common_pool_policy<__pool, true> cpolicy_type; typedef __per_type_pool_policy<char, __pool, true> tpolicy_type; typedef __per_type_pool_policy<unsigned char, __pool, true> upolicy_type; typedef __gnu_cxx::__mt_alloc<char, cpolicy_type> callocator_type; typedef __gnu_cxx::__mt_alloc<char, tpolicy_type> tallocator_type; typedef __gnu_cxx::__mt_alloc<char, upolicy_type> uallocator_type; typedef __gnu_cxx::__pool_base::_Tune tune_type; callocator_type ca; tallocator_type ta; uallocator_type ua; void *tf(void *arg) { callocator_type::pointer p1 = ca.allocate(128); callocator_type::pointer p2 = ca.allocate(5128); ca.deallocate(p1, 128); ca.deallocate(p2, 5128); int idx = (int) (long) arg; if (idx & 1) sleep (1); else sleep (1024); return NULL; } void *tf2(void *arg) { tallocator_type::pointer p1 = ta.allocate(128); tallocator_type::pointer p2 = ta.allocate(5128); ta.deallocate(p1, 128); ta.deallocate(p2, 5128); int idx = (int) (long) arg; if (idx & 1) sleep (1); else sleep (1024); return NULL; } void *tf3(void *arg) { uallocator_type::pointer p1 = ua.allocate(128); uallocator_type::pointer p2 = ua.allocate(5128); ua.deallocate(p1, 128); ua.deallocate(p2, 5128); int idx = (int) (long) arg; if (idx & 1) sleep (1); else sleep (1024); return NULL; } int main() { tune_type t_opt(16, 5120, 32, 5120, 20, 10, false); ca._M_set_options(t_opt); pthread_t th[48]; for (int i = 0; i < 16; ++i) pthread_create (&th[i], NULL, tf, (void *) (long) i); callocator_type::pointer p1 = ca.allocate(128); callocator_type::pointer p2 = ca.allocate(5128); ca.deallocate(p1, 128); ca.deallocate(p2, 5128); sleep (3); tune_type t_opt2(16, 5120, 32, 5120, 36, 10, false); ta._M_set_options(t_opt2); for (int i = 16; i < 32; ++i) pthread_create (&th[i], NULL, tf2, (void *) (long) i); tallocator_type::pointer p3 = ta.allocate(128); tallocator_type::pointer p4 = ta.allocate(5128); ta.deallocate(p3, 128); ta.deallocate(p4, 5128); sleep (3); tune_type t_opt3(16, 5120, 32, 5120, 52, 10, false); ua._M_set_options(t_opt3); for (int i = 32; i < 48; ++i) pthread_create (&th[i], NULL, tf3, (void *) (long) i); uallocator_type::pointer p5 = ua.allocate(128); uallocator_type::pointer p6 = ua.allocate(5128); ua.deallocate(p5, 128); ua.deallocate(p6, 5128); sleep (3); return 0; } -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22309
