The system’s crashreporter_annotations_t structure was always present
as version 4 since Mac OS X 10.7. In OS X 10.11, it is now present as
version 5. It has also grown from 56 to 64 bytes per otool examination
of CoreFoundation’s __DATA,__crash_info section. The extra 8 bytes are
presumed to be a new field at the end of the structure, although this
is not confirmed.
The existing MachOImageAnnotationsReader.CrashAbort test only validated
that the “message” field in crashreporter_annotations_t was recovered
correctly, but
MachOImageAnnotationsReader::ReadCrashReporterClientAnnotations() also
recovers the “message2” field. A new test,
MachOImageAnnotationsReader.CrashModuleInitialization, is added to
ensure that the “messgae2” field can be recovered properly.
This change will resolve warnings such as:
[pid:tid:yyyymmdd,hhmmss.uuuuuu:WARNING
