[2/2] MachOImageReader.Self_DyldImages (20 ms)
2 tests failed:
    MachOImageReader.Self_DyldImages
(../../third_party/crashpad/crashpad/snapshot/mac/mach_o_image_reader_test.cc:535)
    MachOImageReader.Self_MainExecutable
(../../third_party/crashpad/crashpad/snapshot/mac/mach_o_image_reader_test.cc:500)


(Some of the tests require data files, but these two don't, hence the
--gtest_filter.)

Works fine with ld.
