The first release candidate for GCC 9.2 is available from https://gcc.gnu.org/pub/gcc/snapshots/9.2.0-RC-20190805/ ftp://gcc.gnu.org/pub/gcc/snapshots/9.2.0-RC-20190805
and shortly its mirrors. It has been generated from SVN revision 274111. I have so far bootstrapped and tested the release candidate on x86_64-linux and i686-linux. Please test it and report any issues to bugzilla. If all goes well, I'd like to release 9.2 on Monday, August 12th.
