Looking for C-to-anything transpilers

I’m looking for languages that have three properties:

(1) Must have weak memory safety. The language is permitted to crash on an out -of-bounds array reference or null pointer, but may not corrupt or overwrite memory as a result.

(2) Must have a transpiler from C that produces human-readable, maintainable code that preserves (non-perverse) comments. The transpiler is allowed to not do a 100% job, but it must be the case that (a) the parts it does translate are correct, and (b) the amount of hand-fixup required to get to complete translation is small.

(3) Must not be Go, Rust, Ada, or Nim. I already know about these languages and their transpilers.
