Also try
   $ ~/local/bin/valgrind -d -d -d -v -v -v --leak-check=yes ./clock_gettime CLOCK_MONOTONIC

and look for debug symbol loading such as:
-----
--25057:1:main     Load initial debug info
--25057-- Reading syms from /usr/bin/date
--25057--    svma 0x0000401ad0, avma 0x0000401ad0
--25057--   Considering /usr/lib/debug/.build-id/08/884e015589393715fa4c5d3e9a4ab0d1541e99.debug ..
--25057--   .. build-id is valid
