Bug#619550: File::Temp CLEANUP + chdir gotcha still remains

[Joey Hess]

Package: perl-modules
Version: 5.10.1-18
Severity: normal

Bug #479317 explains a gotcha with use of File::Temp::tempdir(CLEANUP => 1).
If the code chdirs into the temp dir, which is a common thing to do,
and then exits without chdiring out, which is not an uncommon thing,
the cleanup code will fail to run.

The bug was closed because it was at least made not to crash the
program. However, this gotcha still remains. A program that has
combined these two common things will be subject to emitting strange
error messages:

cannot remove path when cwd is /home/e-test/tmp/cQei_Q1aVi

.. and leaving behind temp dirs.

I now have at least 3 programs that work around this problem by

END {
	chdir("/)";
}

It's very annoying to have to remember this bug and add this to my code
every time I pull File::Temp into a program.
