We fixed this problem in OpenBSD so you can probably just adapt the indentation changes from: https://github.com/openbsd/src/commit/1e0c6b38375efb02b888b583b475861337640240 https://github.com/openbsd/src/commit/f185ba58eb4e17172f33aba354b7b635e52cea2c The test program does not generate warnings with clang 13 on OpenBSD. - todd
