gmake[5]: Entering directory '/home/op/w/guile/test-suite/standalone'
PASS: test-system-cmds
it seems to work on OpenBSD 7.3 :)
but note that our libc doesn't have posix_spawn_file_actions_addclosefrom_np,
so this is using the "racy" code path.
Just for curiosity, as it's outside the scope of the bug, what's the
reason posix_spawn was used instead of a more classic fork() +
closefrom()?
Thanks,
