It's also relatively close to when we bumped the CI to QEMU v8.1.0 (~9 days afte= r). It can clearly be seen on the risc-v CI dashboard: https://patrick-rivos.github.io/gcc-postcommit-ci/gcv where the fortran failures for the rv32gcv target goes from ~23 -> ~15 failures and back agai= n. I'm investigating locally but not making much headway. Thought I'd chronicle what I learn in a bugzilla in case anyone else has insight into what this m= ight be. Marking this as a testsuite framework issue as that's my best guess current= ly. I'll keep this issue updated as I investigate more.=
