Send bug (error) reports, questions and comments to the mailing list

Please use the 'mysqlbug' script when posting bug reports or questions
about MySQL. mysqlbug will gather some information about your system
and start your editor with a form in which you can describe your
problem. Bug reports might be silently ignored by the MySQL
maintainers if there is not a good reason included in the report as to
why mysqlbug has not been used. A report that says 'MySQL does not
work for me. Why?' is not considered a valid bug report.

The mysqlbug script can be found in the 'scripts' directory of the
distribution, that is '<where-you-installed-mysql>/scripts'.
Something went wrong with that request. Please try again.
