Also, the darwin10 generated 1.s can be reassembled and relinked under darwin11 and the resulting 1.exe runs fine. 2) 30_threads/recursive_mutex/try_lock/1.cc compiled under darwin11 using -mmacosx-version-min=10.6 fails when run under either darwin11 or darwin10. Using the 1.s generated above to reassemble and relink under darwin10 still shows the execution failure.
