| 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. | |
