26 ###
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.
