| | 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. |
