Description:
Info
According to Abseil's documentation, the hash function cannot ensure consistent hash values in the case of dynamic linking: https://github.com/abseil/abseil-cpp/blob/master/absl/hash/hash.h#L43-L46 // `absl::Hash` may also produce different values from different dynamically // loaded libraries. For this reason, `absl::Hash` values must never cross // boundaries in dynamically loaded libraries (including when used in types like // hash containers.) Even though we don't use dynamic linking for production builds we use it on some evergreen workflows. We need to understand if this is really a problem for us.
