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
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
+ http://sourceware.org/bugzilla/
-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.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[ **] 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.
-[ **] If a DSO is using implicitly libpthread and the application itself
- does not there is a name lookup problem. E.g., the function fork()
- will be found in the libc.so instead of libpthread since the thread
- library is behind the libc. To correct this problem it must *not*
- be relied on the currently still enabled handling of weak symbols
- in the dynamic linker. Instead explicit tests for the availability
- of the libpthread version are needed. [PR libc/2325]
-
[ *] The precision of the `sinhl' and/or `asinhl' function do not seem
to be the best.
[ *] 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.
-
-[ *] The regex implementation has various other problems, like limitations
- of the expression size etc. [PR libc/1570, PR libc/1777]
-
- None of these can be fixed without a rewrite.
-
[ *] 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
of the whole LC_COLLATE description.
[ *] Some of the functions which also handled IPv6 are currently broken.
- This includes getaddrinfo() and getnameinfo(). IPv4 handling of
+ 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.
