Yes, when debug is active, those error messages are expected (as part of the trial-and-error to autodetect).
This bug is fixed in v3.20.0.

Thanks for the flagging. Can you suggest a way to replicate this problem without having to fully compile from scratch the most recent gcc14 candidate (e.g., some Docker image)?

I don't think there are docker images for gcc itself, but you could use a gentoo image, and build gcc-14 with portage.

Let me see. I think there might be something I can arrange. I will get back to you.

OK, try https://jwakely.github.io/pkg-gcc-latest/. They're unofficial builds from one of the GCC maintainers.
The example Dockerfile on that page works for me:
FROM ubuntu:latest
RUN apt-get update -y
RUN apt-get install -y build-essential wget
RUN wget --quiet https://kayari.org/gcc-latest/gcc-latest.deb
RUN dpkg -i gcc-latest.deb
RUN /opt/gcc-latest/bin/gcc --versionwith:
docker build -t gcc gcc/
docker run -it gccfrom pycryptodome.

Thanks @thesamesam!
Unfortunately, with that GCC14 version and OS, I can't reproduce the problem (as in, the library builds fine with export CFLAGS="-O2 -lto".
@kostadinsh if this is still a problem for you, can you also retry by setting PYCRYPTODOME_DEBUG=1, then you get a complete dump of all the autodetect logic.

I think I found the issue, and pushed a fix to master (b408368). Please try if you have a chance.
