List of known bugs (certainly very incomplete)
	    ----------------------------------------------

Time-stamp: <1999-12-31T14:42:14-0800 drepper>

This following list contains those bugs which I'm aware of.  Please
make sure that bugs you report are not listed here.  If you can fix one
of these bugs/limitations I'll certainly be glad to receive a patch.

Another source of information about bugs is the problem data base of the
GNU project.  There is an easy to use WWW interface available at

       http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl

I would appreciate it very much if you could verify the problem was not
reported before by looking through the database.  To make the information
in this database as useful as possible please report bugs always using the
`glibcbug' shell script which gets installed with GNU libc.  Before reporting
a bug please check the FAQ since it discusses also a lot of problematic
situations.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Severity: [  *] to [***]

[ **]  Closing shared objects in statically linked binaries most of the
       times leads to crashes during the dlopen().  Hard to fix.

[ **]  There are problems with signal handling when using LinuxThreads.

[ **]  The RPC code is not 64 bit clean.  This is getting slowly fixed
       but expect incompatible changes on 64 bit platforms like Alpha.

[  *]  The precision of the `sinhl' and/or `asinhl' function do not seem
       to be the best.

[  *]  On Linux, there should be a way to prevent defining the symbol
       NGROUPS_MAX in the <linux/limits.h> header file.  In glibc it
       is defined in <posix1_lim.h> which must not make the other
       symbols in <linux/limits.h> available.
       [PR libc/140]

[  *]  The libm-ieee `gamma' function gives wrong results (at least for
       -0.5).

[  *]  The libm-ieee `scalb' function gives wrong results for
       non-integral second parameters.

[  *]  Collation symbol and equivalence class handling in regex are not
       yet 100% correct.
       - [. .] at end of a range does not work
       - [. .] and [= =] do not handle collating symbols (where a symbol
         stands for multiple character) and multibyte character in
         general not correctly.

       This is *extremely* hard to fix since regex has to be rewritten
       completely.
