Submitting Bug Reports using GNATS gnatsweb and gccbug GNATS, the GNU bug tracking system, is used to track GCC bug reports. Before submitting a bug report, please read the [1]general instructions. The preferred way to submit a bug report is by means of the [2]gnatsweb interface. Make sure you include an e-mail address, so we can inform you when the status of your report changes. Another way is to use the gccbug program that is automatically installed with current versions of GCC, which submits the bug report by e-mail. Both techniques use the same GNATS bug database. Filling out a report The bug report form provides a number of fields; you'll need to fill-out most of those (as indicated below) to provide a complete report. The fields have the following purpose: Originator Your name. Organization Your organization. You can leave this field blank. Confidential This field is unused and set to 'no'. All bug reports, including sample code, are publicly accessible. Synopsis A one-line description of the problem; something like "GCC 2.95 does not foo", "objc crashes when doing bar". Severity Can be one of critical GCC is completely not operational; no work-around known. serious GCC is not working properly; a work-around is possible. non-critical Report indicates minor problem. Priority Can be one of high A solution is necessary as soon as possible. This is reserved to GCC maintainers. medium The problem should be solved in the next release. low The problem should be solved in a future release. Category This indicates the GCC subproject which is affected by the problem. Currently, it can be one of ada A problem with the Ada compiler, libraries or tools. bootstrap GCC fails to bootstrap. This should be filed only if a bootstrap failure prevails for an extended period of time (at least one week) on any platform (and possibly not-so-common conditions like a read-only srcdir), or non-mainstream platforms. c++ A problem with the C++ compiler. c A problem with the C compiler. debug A problem with generating debugging information. fortran A problem with the Fortran compiler. java A problem with the Java compiler. libf2c A problem in the Fortran runtime library. libgcj A problem in the Java runtime library. libobjc A problem in the Objective C runtime library. libstdc++ A problem in the Standard C++ runtime library. middle-end A problem in the internal compiler passes. objc A problem with the Objective C compiler. optimization A problem only occurring under optimization. preprocessor A problem with the C preprocessor. target The problem depends on the specific target architecture. web There is an error or omission on the Web pages. other The problem is in none of these categories. Class A classification of the problem; one of doc-bug The documentation is incorrect. accepts-illegal GCC fails to reject erroneous code. rejects-legal GCC gives an error message for correct code. wrong-code The machine code generated by GCC is incorrect. ice-on-legal-code GCC gives an Internal Compiler Error (ICE) for correct code. ice-on-illegal-code GCC gives an ICE instead of reporting an error. pessimizes-code GCC misses an important optimization opportunity. sw-bug Software bug of some other class than above. change-request A feature in GCC is missing. support I need help with GCC. Release GCC version, as obtained from 'gcc -v' (one line). Environment Information about your operating system version, hardware architecture, and environment settings that affect GCC. Description Precise description of the problem. You should put the error messages printed by GCC here; source code should go into the next section. How-To-Repeat Please put the complete source code to reproduce the problem here. The gccbug script currently does not support file attachments. Instead, if you have multiple files, include them uuencoded (compressing them before if they are large). If you use gnatsweb, you can use the file attachments button instead. Fix How to correct or work around the problem, if known (multiple lines).
