Rodrigo Pinheiro Marques de Araújo added the comment: Sorry for that. I’m not able to make a little example to reproduce this bug. It’s happens during Django tests on a very large code base. A interest thing is that not happens with “-X dev” parameters. Please, any suggestions how I can get more details about this bug? -- ___ Python tracker <https://bugs.python.org/issue34087> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
