The assert in __deregister_frame_info_bases takes that into account. In the non-fast-path case however is not aware of program shutdown, which caused a compiler error on such platforms. We fix that by introducing a constant for in_shutdown in non-fast-path builds. We also drop the destructor priority, as it is not supported on all platforms and we no longer rely upon the priority anyway. libgcc/ChangeLog: * unwind-dw2-fde.c: Introduce a constant for in_shutdown for the non-fast-path case. Drop destructor priority. --- diff --git a/libgcc/unwind-dw2-fde.c b/libgcc/unwind-dw2-fde.c index d237179f4ea9..3c0cc654ec0e 100644 --- a/libgcc/unwind-dw2-fde.c +++ b/libgcc/unwind-dw2-fde.c @@ -51,7 +51,7 @@ static struct btree registered_frames; static bool in_shutdown; static void -release_registered_frames (void) __attribute__ ((destructor (110))); +release_registered_frames (void) __attribute__ ((destructor)); static void release_registered_frames (void) { @@ -67,6 +67,8 @@ static void init_object (struct object *ob); #else +/* Without fast path frame deregistration must always succeed. */ +static const int in_shutdown = 0; /* The unseen_objects list contains objects that have been registered but not yet categorized in any way.
