patch
The DenseMapInfo instance for std::pair's second Tombstone is set to be the
empty key, see below and the attached patch:
template<typename T, typename U>
struct DenseMapInfo<std::pair<T, U> > {
typedef std::pair<T, U> Pair;
typedef DenseMapInfo<T> FirstInfo;
typedef DenseMapInfo<U> SecondInfo;
static inline Pair getEmptyKey() {
return std::make_pair(FirstInfo::getEmptyKey(),
SecondInfo::getEmptyKey());
}
static inline Pair getTombstoneKey() {
return std::make_pair(FirstInfo::getTombstoneKey(),
SecondInfo::getEmptyKey());
I believe the last line should read:
return std::make_pair(FirstInfo::getTombstoneKey(),
SecondInfo::getTombstoneKey());
