Reporting a LaTeX bug
The LaTeX team supports LaTeX, and will deal with bona fide bug reports. Note that the LaTeX team does not deal with contributed packages — just the software that is part of the LaTeX distribution itself: LaTeX and the “required” packages. Furthermore, you need to be slightly careful to produce a bug report that is usable by the team. The steps are:
- Are you still using current LaTeX? Maintenance is only available for sufficiently up-to-date versions of LaTeX
- Prepare a "minimum" file that exhibits the problem. Ideally, such a file should contain no contributed packages — the LaTeX team as a whole takes no responsibility for such packages (if they're supported at all, they're supported by their authors). The “minimum” file should be self-sufficient: if a member of the team runs it in a clean directory, on a system with no contributed packages, it should replicate your problem. See the LaTeX team guidelines for more advice.
- Run your test file through LaTeX: the bug report should include the
.logfile that this process creates.
- Log an issue in the GitHub tracker.
