OS X 10.11 introduces System Integrity Protection. One facet of that forbids code injection into system executables. A Crashpad test checks that information can be recovered from dyld in early-launch crashes by requesting dyld load a nonexistent library with DYLD_INSERT_LIBRARIES. The executable was meaningless but a system-provided executable, /usr/bin/true, was used for convenience. This test hung on OS X 10.11 because DYLD_INSERT_LIBRARIES was ignored for the system executable, and no crash occurred. The test waited for a crash that would never come. A custom no-op executable, crashpad_snapshot_test_no_op, is provided as an executable that does work with DYLD_INSERT_LIBRARIES.
