I want extern "fil-C"

Why isn't fil-C ABI compatible with C?

Apparently this was done intentionally. The rationale given is that we don't want to allow non-safe C to be used in fil-C programs. Fair enough.

But why should we prevent fil-C programs to be used from Rust (or C, for that matter)?

I don't understand much about compilers, but presumably allowing one would also allow the other?

There is a solution that Mozilla uses in prod for legacy C codecs:

It's not a replacement for Fil-C's role as a precise ASAN/Valgrind, but it works great if you want to call a C library without letting it freely spray caller's memory.
