A second release candidate for GCC 9.4 is available from
https://sourceware.org/pub/gcc/snapshots/9.4.0-RC-20210528/ and shortly its mirrors. It has been generated from git commit ebfe8b28d40746ff33724bd5b9ade2552e619213, containing a build fix with recent kernel headers and fixes for a few C++ issues, notably PR100797, a late spotted regression from GCC 9.3. I have so far bootstrapped and tested the release candidate on x86_64-unknown-linux-gnu. Please test it and report any issues to bugzilla. If all goes well this time I'd like to release 9.4 on Tuesday, June 1st.
