I submitted a minimized bug report: https://github.com/llvm/llvm-project/issues/64019 Hopefully it will be fixed soon, I can't see any good workarounds on the FreeBSD side. This bug report is just to track the issue on the FreeBSD si= de, in case other folks run into it. --=20 You are receiving this mail because: You are the assignee for the bug.=
