Exactly. **temporary** files are just that: temporary.

You don't expect them to be there after a reboot, or the next time your
program runs, or whatever.

If you want files to remain somewhere, you put them somewhere specific that is
**not** one of the tmp directories. And you name it such that there can be
multiple instances of it, such as 
     '/some-permanent-directory/my_program_errors-[PID-NUMBER]'

Any well-behaved program should destroy all of its temporary files after it
has finished with them. 

That doesn't always happen.  I'm looking at you GTK with your /tmp/gtk_errs
that might end up being owned by root, unable to be removed by non-root
users, and which causes GTK programs not owned by root to crash:

   m70t [jvs] /home/jvs > gparted
   bash: /tmp/gtk_errs: Permission denied
   m70t [jvs] /home/jvs >

Regards.
