labath added a comment.
The implementation looks nice and clean. I have only some stylistic comments
giving it finishing touches..

What's the anticipated usage of this function? I am wondering whether it
shouldn't clear the cached data (m_header, m_directory_map) as well. Or maybe,
since you already have a matching contructor, just remove the function and have
the user construct a new object if he needs to (?)

(nit) if you include <cstring>, it's not a `C` include :)
I'd put that under `C++`

Does the user need to know that you are returning an iterator? The map sounds
like an implementation detail. If you don't have any usages for that in mind,
it would be just cleaner to return the `MinidumpLocationDescriptor` (or maybe a
reference to it) directly. Then you could remove the typedef above as well...

Should we abort upon encountering the first invalid thread?
I am thinking of a situation where a corrupt file claims to have UINT32_MAX
threads, and we end up spinning here for quite a long time...

Let's change these into (anonymous) enums as well. We should avoid macros when
possible.

----------------
Since it's the parser who handles setting the byte order and such, maybe we
should just pass the data buffer to it, and let it construct the data extractor
internally. Would that work?
