Tag Info

This tag is reserved for questions where the problem has been vetted by this community and the observed behavior is confirmed to be a bug. Please do not use this tag for new questions. Please use the standard bugs header instead of version tags in conjunction with this tag.

A bug is an error/mistake in the software that produces an incorrect or unexpected result or behavior.

This tag will be added to questions about problems that have subsequently been confirmed by other users to be caused by bugs in Mathematica. It should not be used when asking new questions. If you know that a certain behavior is a confirmed bug, please report it to Wolfram Support instead (or e-mail support@wolfram.com).

Please ensure that all questions with this tag have clear instructions on how to reproduce the bug. The instructions should make it easy to quickly test if the bug exists in a certain version of Mathematica.

[For known-version bugs]:

Bug introduced in X.X and fixed in X.X.X

with MarkDown code

**Bug introduced in X.X and fixed in X.X.X**


And for open-ended versioning:

Bug introduced in X.X or earlier and persisting through X.X.X or later

with MarkDown code

**Bug introduced in X.X or earlier and persisting through X.X.X or later**


There is a bug tracker at http://packagedata.net/bugtracker/mma-bug-tracker.zip that uses this header to generate a bug report (example, generated on 17th of May, 2017)
