This patch broke bootstrap on AIX and probably other targets.
#ifdef ATOMIC_FDE_FAST_PATH
#include "unwind-dw2-btree.h"
static struct btree registered_frames;
static bool in_shutdown;
...
#else
in_shutdown only is defined for ATOMIC_FDE_FAST_PATH but used in code /
asserts not protected by that macro.
gcc_assert (in_shutdown || ob);
return (void *) ob;
}
I am sorry for that, I did not consider that my test machines all use
the fast path.
I think the problem can be fixed by the trivial patch below, I will
commit that after I have tested builds both with and without fast path.
Best
Thomas
