Auto merge of #1419 - gnzlbg:ctest_fix, r=gnzlbg

Update ctest version

The latest ctest version enabled the ABI roundtrip test by default, in which we initialize all types in Rust by default to some random bit-pattern, pass them to C, verify, modify, pass back to Rust, and verify.

This catches issues in the call ABI / calling convention.

This PR will silence those here for now.
