From @eserte

This is a bug report for perl from slaven@rezic.de\, generated with the help of perlbug 1.40 running under perl 5.19.9.

With perl 5.19.9 sometimes taint errors happen which are usually not reproducible. One of these errors happened in the perl test suite itself:

dist/Locale-Maketext/t/90_utf8 ................................ Insecure dependency in eval while running with -T switch at ../../lib/Locale/Maketext.pm line 754. # Looks like you planned 3 tests but ran 2. # Looks like your test exited with 255 just after 2. FAILED--expected 3 tests\, saw 2

A subsequent run of this test did not show the error anymore.

Similar errors happened while testing CPAN modules. My smokers are running on a physical FreeBSD 9.2 and virtual FreeBSD 9.2 and 10.0\, and the error may happen on all of these. The errors look like this:

fail.PGObject-Type-DateTime-1.00.001.amd64-freebsd.9.2-release.1393056306.86194.rpt:# Error: Insecure dependency in require while running with -T switch at /usr/perl5.19.9/lib/5.19.9/parent.pm line 20. fail.PGObject-Type-DateTime-1.00.amd64-freebsd.9.2-release.1392949154.95426.rpt:# Error: Insecure dependency in require while running with -T switch at /usr/perl5.19.9/lib/5.19.9/parent.pm line 20. ime.pm line 317. fail.DBIx-Class-RDBOHelpers-0.11.amd64-freebsd.10.0-release.1393874639.87156.rpt:# Insecure dependency in require while running with -T switch at /usr/perl5.19.9/lib/site_perl/5.19.9/Module/Runtime.pm line 317. fail.Dezi-Admin-0.005.amd64-freebsd.10.0-release.1393999037.94662.rpt:# Error: Insecure dependency in require while running with -T switch at /usr/perl5.19.9/lib/5.19.9/parent.pm line 20. fail.Template-Flute-0.0104.amd64-freebsd.9.2-release.1394219187.21536.rpt:# Failure parsing specification: Insecure dependency in eval while running with -T switch at /usr/perl5.19.9/lib/site_perl/5.19.9/Parse/RecDescent.pm line 1208. fail.XML-RSS-1.54.amd64-freebsd.10.0-release.1393790899.8222.rpt:Insecure dependency in require while running with -T switch at /usr/perl5.19.9/lib/site_perl/5.19.9/Module/Runtime.pm line 317.

It's not only FreeBSD. This problem may happen also on Linux systems:

I cannot remember that this kind of error happened with perl 5.19.8 or earlier.

Template::Flute got a new upload today which fails its tests\, so I did not test with valgrind. Testing 0.0105 with current bleadperl does not have the issues valgrind reported for 5.19.9 anymore. But a memory leak is reported:

Gone are the cited messages with bleadperl\, but a memory leak is reported:

Note\, that my /lib/x86_64-linux-gnu/ld-2.17.so is indicated by valgrind\, so it may be that the remaining leaks stem from there.

Valgrind knows something.

uuid.t in DBIx-Class-UUIDColumns-0.02006:

But testing with current bleadperl v5.19.9-123-gd6f4d13 these messages are gone. And no memory leak is reported.

t/01-helloworld.t in Template-Flute-0.0105:

Template::Flute got a new upload today which fails its tests\, so I did not test with valgrind. Testing 0.0105 with current bleadperl does not have the issues valgrind reported for 5.19.9 anymore. But a memory leak is reported:

==24616== LEAK SUMMARY: ==24616== definitely lost: 133\,247 bytes in 18\,495 blocks ==24616== indirectly lost: 0 bytes in 0 blocks ==24616== possibly lost: 15\,216\,974 bytes in 7\,586 blocks ==24616== still reachable: 7\,849\,024 bytes in 47\,200 blocks ==24616== suppressed: 0 bytes in 0 blocks

t/02_formatting.t of DateTime-Format-RFC3339-v1.0.5

Gone are the cited messages with bleadperl\, but a memory leak is reported:

==23433== LEAK SUMMARY: ==23433== definitely lost: 11\,788 bytes in 880 blocks ==23433== indirectly lost: 0 bytes in 0 blocks ==23433== possibly lost: 5\,295\,710 bytes in 3\,179 blocks ==23433== still reachable: 4\,313\,336 bytes in 32\,896 blocks ==23433== suppressed: 0 bytes in 0 blocks

Note\, that my /lib/x86_64-linux-gnu/ld-2.17.so is indicated by valgrind\, so it may be that the remaining leaks stem from there.

Be sure you read perlhacktips about valgrind and memory leaks\, if you haven't. In particular\,

NOTE 2: To minimize the number of memory leak false alarms (see "PERL_DESTRUCT_LEVEL" for more information)\, you have to set the environment variable PERL_DESTRUCT_LEVEL to 2. For example\, like this:

* env PERL_DESTRUCT_LEVEL=2 valgrind ./perl -Ilib ...

Here's my valgrind output on Olson-Abbreviations-0.04 (perl5.19.9 on FreeBSD 10.0). S_regatom also appeared in Andreas' valgrind outputs:

Similar errors happened while testing CPAN modules. My smokers are running on a physical FreeBSD 9.2 and virtual FreeBSD 9.2 and 10.0\, and the error may happen on all of these. The errors look like this:

This may have been fixed in ed885487570a4a0046b0cb32a477526f8f016d93.

So in order for us to really consider this a problem\, we need to see it on blead\, and for the leaks to still be there if valgrind is run under PERL_DESTRUCT_LEVEL=2

Thanks for the pointer\, Karl!

PERL_DESTRUCT_LEVEL=2 does not help on IKEGAMI/DateTime-Format-RFC3339-v1.0.5.tar.gz\, there is a remaining memory leak:

==27242== LEAK SUMMARY: ==27242== definitely lost: 11\,788 bytes in 880 blocks ==27242== indirectly lost: 0 bytes in 0 blocks ==27242== possibly lost: 5\,295\,710 bytes in 3\,179 blocks ==27242== still reachable: 4\,313\,097 bytes in 32\,901 blocks ==27242== suppressed: 0 bytes in 0 blocks

The same memory leak was already in 5.18.2. It was smaller in 5.16.3 (definitely lost: 9\,755 bytes in 295 blocks). And it was not there in 5.14.4. S_doeval is involved in all reported allocations\, in many stacks more than once.

Whereas on HORNBURG/Template-Flute-0.0105.tar.gz the memory leak goes away with PERL_DESTRUCT_LEVEL=2.
