That's still unresolved (not blaming you!); those intermittent failures are still seen. I've not yet been able to look into your follow-on discussion and WIP patch 'acc_prof-parallel-barrier-1.diff' "Add barrier, hack" in detail. As part of the og12 branch setup, Kwok then had to put og12 commit b845d2f62e7da1c4cfdfee99690de94b648d076d "Revert changes to acc_prof-init-1.c and acc_prof-parallel-1.c" on top of your og12 commit 719f93c8618a134f90b5b661ab70c918d659ad05 "OpenACC profiling-interface fixes for asynchronous operations", and that stuff is now again conflicting with GCC master branch work that I need to cherry-pick into og12 branch. Therefore, I'm now reverting this on og12 branch -- with the intention to resolve that issue on master branch, eventually (but no promises, when). Pushed to devel/omp/gcc-12 branch commit 1818bab2ce9f11d8dde5b378f580971b87a5c4ff 'Revert "Revert changes to acc_prof-init-1.c and acc_prof-parallel-1.c"', and commit b8beaa8447ed3c1637e8f93a08c0e47b5709290f 'Revert "OpenACC profiling-interface fixes for asynchronous operations"', see attached.
