McEliece keys, in particular, take up a large amount of stack space.
Not only do we currently have to configure this manually for builds for each individual platform,
but since the stack space is set in compile time, this RAM will be held on to indefinitely,
even while no keys are being generated.
This pull request solves both issues by running the KEM key generation in a separate thread.
This allows the stack to be created in runtime, which has two benefits:
Running as before is still supported through a feature flag.
EDIT:
The macos CI build couldn't find libcrypto. I'm not sure why this is but does not seem to be an issue related to this update. I have commented out
RUST_MIN_STACKinci.ymlas it is no longer needed.I have also commented out
macos-latestfrom the OS matrix as it was getting in the way of the windows/ubuntu builds runing their test. Once the build issue has been overcome on your side, this will have to be uncommented again.
