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.
|
|
|
|
[ **] 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.
|
|
|
|
[ *] 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.
|
|
|
|
[ *] 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
|
|
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.
|
|
This includes getaddrinfo() and getnameinfo(). IPv4 handling of
|
|
these functions is OK though and there are patches available to fix
|
|
the IPv6 code as well.
