No. Intrinsics method signatures are not associated to LibC::SizeT.
This PR is short one, without changing of rules of the game.

No idea what you're talking about. Why spray the definition of size_t all over the codebase when it already exists.
Use LibC::SizeT.new instead of to_size_t and you don't need this method.

Yes, we need to introduce generic SizeT and OffsetT types, or change Intrinsics contracts, but it should be discussed and introduced by another PR.
This PR just fixes contract implementation.

Just note that it's short fix for crystal-lang#4589 only.

I have no idea why the CI isn't broken but isn't this passing 32bit ints to something expecting a U64?

Dislike this as it actually returns a different type depending on the architecture. I'd prefer a SizeT. |

This is a palliative. Will rework using SizeT and OffsetT. |

Sorry, that doesn't solve anything. It still relies on |

@konovod thanks. was fixed with #4624. @ysbaddaden thanks too. |

No generic SizeT, OffsetT introduced here.
