This seems to be an incompatability introduced in perl 5.10.
pristine-tar creates a temp directory with File::Temp and chdirs into
it. At exit, File::Temp calls rmtree to delete the temp directory. After
deleting the directory, rmtree tries to chdir back to that location so
as to not "leave the client code in an unexpected directory". But it's
deleted the directory, so of course this fails!
Simple test case:
joey@kodama:~>perl -e 'use File::Temp; my $t=File::Temp::tempdir(TMPDIR => 1, CLEANUP => 1); mkdir("$t/foo"); chdir "$t/foo"; print "now exiting\n"'
now exiting
cannot chdir to /home/joey/tmp/7mbcKCVWya/foo from /home/joey/tmp/7mbcKCVWya: No such file or directory, aborting. at /usr/share/perl/5.10/File/Temp.pm line 893
END failed--call queue aborted.
I doubt this only affects pristine-tar. I have put in the following
workaround in it, but really feel that this bug needs to be fixed in
perl, so reassigning.
# Workaround for bug #479317 in perl 5.10.

chdir("/");
