Reporting Bugs
**************

   If you think you have found a bug in the GMP library, please
investigate it and report it.  We have made this library available to
you, and it is not too much to ask you to report the bugs you find.

   Before you report a bug, check it's not already addressed in Note:
Known Build Problems, or perhaps Note: Notes for Particular
Systems.  You may also want to check `http://swox.com/gmp/' for
patches for this release.

   Please include the following in any report,

   * The GMP version number, and if pre-packaged or patched then say so.

   * A test program that makes it possible for us to reproduce the bug.
     Include instructions on how to run the program.

   * A description of what is wrong.  If the results are incorrect, in
     what way.  If you get a crash, say so.

   * If you get a crash, include a stack backtrace from the debugger if
     it's informative (`where' in `gdb', or `$C' in `adb').

   * Please do not send core dumps, executables or `strace's.

   * The configuration options you used when building GMP, if any.

   * The name of the compiler and its version.  For `gcc', get the
     version with `gcc -v', otherwise perhaps `what `which cc`', or
     similar.

   * The output from running `uname -a'.

   * The output from running `./config.guess', and from running
     `./configfsf.guess' (might be the same).

   * If the bug is related to `configure', then the contents of
     `config.log'.

   * If the bug is related to an `asm' file not assembling, then the
     contents of `config.m4' and the offending line or lines from the
     temporary `mpn/tmp-<file>.s'.

   Please make an effort to produce a self-contained report, with
something definite that can be tested or debugged.  Vague queries or
piecemeal messages are difficult to act on and don't help the
development effort.

   It is not uncommon that an observed problem is actually due to a bug
in the compiler; the GMP code tends to explore interesting corners in
compilers.

   If your bug report is good, we will do our best to help you get a
corrected version of the library; if the bug report is poor, we won't
do anything about it (except maybe ask you to send a better report).

   Send your report to: <bug-gmp@gnu.org>.

   If you think something in this manual is unclear, or downright
incorrect, or if the language needs to be improved, please send a note
to the same address.
