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

-Severity: [ *] to [***]
+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://sourceware.org/bugzilla/
-[***] Profiling currently does not work with programs using NSS.
+I would appreciate it very much if you could verify the problem was
+not reported before by looking through the database. Before reporting
+a bug please check the FAQ since it discusses also a lot of
+problematic situations.
-[***] At least on Linux/Alpha, there seem to be problems with dynamically
- loading NSS modules in certain situations.
- [PR libc/137]
-[ **] For GNU libc on Linux, there is still no solution for the UTMP
- problem.
- [Among others: PR libc/39]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-[ **] There are problems with signal handling when using LinuxThreads.
+Severity: [ *] to [***]
-[ **] The `cbrtl' function is inaccurate. The algorithm used for `double'
- and `float' is not usable.
+[ **] Closing shared objects in statically linked binaries most of the
+ times leads to crashes during the dlopen(). Hard to fix.
-[ **] Not really a bug, but it could lead to such:
- The RPC code is ugly ugly ugly. It's more or less verbatim taken
- from Sun's code and therefore mostly lacks complete prototypes and
- (more important) the use of `const'. It *definitely* needs to be
- cleaned.
+[ **] 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.
-[ *] The syslog function should print to the console if the LOG_CONS
- flag was given.
- [PR libc/72]
+[ *] 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.
+
+[ *] Several (most?) collation specifications are broken. The code which
+ is currently there is in most cases inherited from the originial
+ author (in case there is a LC_COLLATE specification in the locale
+ file) or is defined using the default (if iso14651_t1 is included).
+
+ In any case we are missing information to correct the specification.
+ If you find the specification for your language be faulty please
+ send a report with instruction on what to fix. You don't have to
+ fix the specification yourself.
+
+ The way it finally should look like (if the generic specification
+ is not correct) can be seen in the sv_SE file. Quite a few changes
+ on top of the generic specification can be made without duplication
+ of the whole LC_COLLATE description.
+
+[ *] Some of the functions which also handled IPv6 are currently broken.
+ IPv6 and IPv4 lookups occasionally happen when not needed. This
+ happens in getaddrinfo() and getnameinfo(). IPv4 handling of
+ these functions is OK though and there are patches available to fix
+ the IPv6 code as well.
