Wait a second here.
As your earlier strace shows, with !ENABLE_FEATURE_MOUNT_NFS
we are using uninitialized file descriptor somewhere.
It's a bug, and it still should be fixed.
Can you do the strace again, with printfs added and FEATURE_MOUNT_NFS
not set (so that it will show "Bad file descriptor" again),
and send me strace log and your modified mount.c with printfs?
