Bug #67713 for Devel-Cover: cover -test spouting "Insecure dependency in open while running with -T switch" errors

When cover -test is ran inside a distribution that contains at least two tests that enable taint mode via the -T argument on the shebang, it causes "Insecure dependency in open while running with -T switch" errors starting from the *second* test : ===================================================================== $ cover5.12.3-64 -test Deleting database /tmp/wut/cover_db cover: running make test OPTIMIZE=-O0\ -fprofile-arcs\ -ftest-coverage OTHERLDFLAGS=-fprofile-arcs\ -ftest-coverage PERL_DL_NONLAZY=1 /home/vince/perl/builds/64/5.12.3/bin/perl5.12.3 "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/1.t .. ok t/2.t .. 1/1 Insecure dependency in open while running with -T switch at /home/vince/perl/builds/64/5.12.3/lib/site_perl/5.12.3/x86_64-linux/Devel/Cover/DB/IO.pm line 79.

Also note that coverage for the test file "t/2.t" appears in the summary report (as well as in the generated html files).
