 Is this a typo? As far as I understand the subject it should be
 
 % cc -g -o sig sig.c -pthread
 
 > % ./sig
 > Fatal error '_pq_remove: Not in priority queue' at line ? in file /usr/src/lib/libc_r/uthread/uthread_priority_queue.c (errno = ?)
 > Abort (core dumped)
 
 Anyway, I cannot reproduce the bug on 4.5-STABLE.
 
 $ rm -f sig
 $ cc -g -o sig sig.c
 $ ./sig
 ^C
 $ rm -f sig
 $ cc -g -o sig sig.c -pthread
 $ ldd sig
 sig:
         libc_r.so.4 => /usr/lib/libc_r.so.4 (0x28065000)
