Before reporting a bug, make sure that it's not a feature as there are more and more divergences between BoosTexter and icsiboost. Read the documentation in the wiki and refer to the source code for technical details.

Then, use the issue reporting tool to give details about the bug:

1. Describe the problem quickly.
2. Give source revision number and relevant build platform info.
3. Upload a small dataset on which the bug can be reproduced (if it only occurs on large datasets, provide a download link for such a data set).
4. Give commands that trigger the bug on that dataset.
