27 ### This test case is to verify that dyld cannot be tricked into loading

28 ### the "same" library twice.

29 ###

30 ### The tricky scenario is:

31 ### 1) a library dyld is to load is specified with a symlink path

32 ### 2) the library the that is the target of the symlink is already loaded

33 ### via a different path. In this case becuase of DYLD_LIBRARY_PATH.
