###### this is how the bug could be reproduced
PS: do have a look at the traceback ::it makes no sense to me, it might to you !

[tirkarthi]

Search gives me bpo-29571 that looks similar to this report. This seems to be locale specific and information on your locale, OS etc would be helpful. Can you please add the output of below?

• python -m test.pythoninfo
• locale
• ./python -m test -v test_re

Thanks

Thanks for the details. This seems to be the same as bpo-29571 where the issue was reported on Ubuntu for en_IN but not happening in Gentoo.
