From fc0477a67641b9ba344de595b7fec2431208f8e6 Mon Sep 17 00:00:00 2001 From: Rickard Green Date: Tue, 24 Jan 2017 19:50:25 +0100 Subject: Atomic reference count of binaries also in non-SMP NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc() --- erts/emulator/beam/break.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'erts/emulator/beam/break.c') diff --git a/erts/emulator/beam/break.c b/erts/emulator/beam/break.c index dfbe1ced47..8020dd484c 100644 --- a/erts/emulator/beam/break.c +++ b/erts/emulator/beam/break.c @@ -647,7 +647,7 @@ bin_check(void) erts_printf("%p orig_size: %bpd, norefs = %bpd\n", bp->val, bp->val->orig_size, - erts_smp_atomic_read_nob(&bp->val->refc)); + erts_refc_read(&bp->val->refc, 1)); } } if (printed) { -- cgit v1.2.3
