Something really fishy is going on here. Note that you get the *same*
file_name with both 5.9.8 and 5.12.3. This is already really strange,
but the stranger thing is that the last component of abstmp and realtmp
changes, becoming lyx_tmpdir.rHrJLJU14712 in one case and
lyx_tmpdir.BOxdOihSBXEp in the other one. Seemingly, they are unrelated
to file_name...

I tried to reproduce your configuration on linux by creating a /tmpriv
symlink pointing to /private/tmp and trying to set the temporary dir
to /tmpriv. I did non succeed because it seems that the temporary
directory cannot be changed and is always /tmp, whatever you set
in Preferences->Paths->Temporary directory !
