--- Comment #1 from Reid Kleckner <rnk at google.com> ---
This was fixed in r306304. We forgot to fill in one of the fields of the debug
directory:
-      // TODO(compnerd) get the file offset
-      D->PointerToRawData = 0;

The dbghelp error message is actually quite helpful, because "MZ" is actually
the magic for a DOS executable header. Our file offset was zero, so it tried to
parse from there, and it printed the unrecognized magic.
