Yes. I assume you've seen this:

Although you might consider a stronger hash function.
Thanks a lot for detailed answer. Another question then:
is computed CRC32 value good hash_value() for unorderd containers?

I mean: say I have a ClassInfo class that keeps the name (string) and a hash
(computed by crc algo) will that work fine (distribution-wise)?

size_t hash_value(const ClassInfo& info)
{
  return info.crcHash_;
}

Cheers,
