| 25 | # This unit test verifies that multiple interposing libraries can all | |
| 26 | # interpose the same function and the result is that they chain together. | |
| 27 | # That is, each one calls through to the next. | |
| 28 | # | |
| 29 | # On Tiger (10.4.0), this test fails with infinite recursion. | |
| 30 | # | |
| 31 | # The function foo() does string appends. This allows us to check: | |
| 32 | # 1) every interposer was called, and 2) they were called in the | |
| 33 | # correct order. | |
