It's the recent changes for O_CLOFORK. Specifically this new test in kern_fork.c:

https://github.com/NetBSD/src/commit/60619b499672007eb37fe9705bb029758c41b4c0#diff-53fa54c22c2d2517d75acab3d1bd240a149638fbdaca8b264fe555b009fde5d2

This causes __clone(2) to fail, if the program has a FD opened with O_CLOFORK
set; and, with the last update to tzcode, it now opens /etc/localtime with that
flag set.

Thomas, can you try again after commenting out that test in kern_fork.c (r1.232)?
