<pre>-a prints archive headers. It should probably emit a warning/error and not do
anything when specified for a regular object file. However, it instead crashes,
because it attempts to dereference a null pointer:
static void DumpObject(ObjectFile *o, const Archive *a = nullptr,
const Archive::Child *c = nullptr) {
...
if (ArchiveHeaders && !MachOOpt)
printArchiveChild(a->getFileName(), *c); // a will be null here
...
}</pre>
</div>
