# Reporting Bugs

A list of known bugs can be found in the ``BUGS'` file included in the GSL distribution. Details of compilation problems can be found in the ``INSTALL'` file.

If you find a bug which is not listed in these files please report it to `bug-gsl@gnu.org`.

All bug reports should include:

- The version number of GSL
- The hardware and operating system
- The compiler used, including version number and compilation options
- A description of the bug behaviour
- A short program which exercises the bug

It is also useful if you can report whether the same problem occurs when the library is compiled without optimization.

Thank you.
