If I use MinidumpStreamType as the keys type then I think I have to specify the getEmptyKey() and getTombstoneKey() functions via DenseMapInfo.
And in the "unsigned" template specialisation of DenseMapInfo:

// Provide DenseMapInfo for unsigned ints.
template<> struct DenseMapInfo<unsigned> {
  static inline unsigned getEmptyKey() { return ~0U; }
  static inline unsigned getTombstoneKey() { return ~0U - 1; }
  static unsigned getHashValue(const unsigned& Val) { return Val * 37U; }
  static bool isEqual(const unsigned& LHS, const unsigned& RHS) {
    return LHS == RHS;

So I should probably add there "special" values in the enum as well in order for it to work?

Yes, forgot to change it ...
