| There are probably bugs in the GNU C library. There are certainly |
| errors and omissions in this manual. If you report them, they will get |
| fixed. If you don't, no one will ever know about them and they will |
| remain unfixed for all eternity, if not longer. |
| |
| <p>It is a good idea to verify that the problem has not already been |
| reported. Bugs are documented in two places: The file <samp><span class="file">BUGS</span></samp> |
| describes a number of well known bugs and the upstream GNU C library |
| bug tracking system has a |
| WWW interface at |
| <a href="http://sources.redhat.com/bugzilla/">http://sources.redhat.com/bugzilla/</a>. The WWW |
| interface gives you access to open and closed reports. A closed report |
| normally includes a patch or a hint on solving the problem. |
| |
| <p>To report a bug, first you must find it. With any luck, this will be the |
| hard part. Once you've found a bug, make sure it's really a bug. A |
| good way to do this is to see if the GNU C library behaves the same way |
| some other C library does. If so, probably you are wrong and the |
| libraries are right (but not necessarily). If not, one of the libraries |
| is probably wrong. It might not be the GNU library. Many historical |
| Unix C libraries permit things that we don't, such as closing a file |
| twice. |
| |
| <p>If you think you have found some way in which the GNU C library does not |
| conform to the ISO and POSIX standards (see <a href="Standards-and-Portability.html#Standards-and-Portability">Standards and Portability</a>), that is definitely a bug. Report it! |
| |
| <p>Once you're sure you've found a bug, try to narrow it down to the |
| smallest test case that reproduces the problem. In the case of a C |
| library, you really only need to narrow it down to one library |
| function call, if possible. This should not be too difficult. |
| |
| <p>The final step when you have a simple test case is to report the bug. |
| Do this at {No value for `REPORT_BUGS_TO'}. |
| |
| <p>If you are not sure how a function should behave, and this manual |
| doesn't tell you, that's a bug in the manual. Report that too! If the |
| function's behavior disagrees with the manual, then either the library |
| or the manual has a bug, so report the disagreement. If you find any |
| errors or omissions in this manual, please report them to the |
| bug database. If you refer to specific |
| sections of the manual, please include the section names for easier |
| identification. |
