The branch stable/13 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=0218596e92204dd3890cd9d1f3fc8fdffb1e770a commit 0218596e92204dd3890cd9d1f3fc8fdffb1e770a Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-12-05 00:28:59 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2023-05-03 00:05:54 +0000 acpica: Quiet a -Wdangling-pointer warning in AcpiUtInitStackPtrTrace. This function intentionally saves a pointer to an on-stack variable in a global as a dubious way of reading the stack pointer.
