Mark Johnston 36f0a34ca6 libthr: Force the thr_wake() symbol to be resolved during initialization ... Otherwise the lock upgrade performed by rtld's load_filtees() can result in infinite recursion, wherein: 1. _rtld_bind() acquires the bind read lock, 2. the source DSO's filtees haven't been loaded yet, so the lock upgrade in load_filtees() cause rtld to jump to _rtld_bind() and release the bind lock, 3. _thr_rtld_lock_release() calls _thr_ast(), which calls thr_wake(), which hasn't been resolved yet, 4. _rtld_bind() acquires the bind read lock in order to resolve thr_wake(), 5. ... See the linked pull request for an instance of this problem arising with libsys. That particular instance is also worked around by commit e7951d0b04.
