1 List of known bugs (certainly very incomplete)

6 This following list contains those bugs which I'm aware of. Please
7 make sure that bugs you report are not listed here. If you can fix one
8 of these bugs/limitations I'll certainly be glad to receive a patch.
10 Another source of information about bugs is the problem data base of the
11 GNU project. There is an easy to use WWW interface available at
13 http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl
15 I would appreciate it very much if you could verify the problem was not
16 reported before by looking through the database. To make the information
17 in this database as useful as possible please report bugs always using the
18 `glibcbug' shell script which gets installed with GNU libc. Before reporting
19 a bug please check the FAQ since it discusses also a lot of problematic

25 Severity: [ *] to [***]
27 [ **] Closing shared objects in statically linked binaries most of the
28 times leads to crashes during the dlopen(). Hard to fix.
30 [ **] There are problems with signal handling when using LinuxThreads.
32 [ **] The RPC code is not 64 bit clean. This is getting slowly fixed
33 but expect incompatible changes on 64 bit platforms like Alpha.
35 [ *] The precision of the `sinhl' and/or `asinhl' function do not seem
38 [ *] On Linux, there should be a way to prevent defining the symbol
39 NGROUPS_MAX in the <linux/limits.h> header file. In glibc it
40 is defined in <posix1_lim.h> which must not make the other
41 symbols in <linux/limits.h> available.
44 [ *] The libm-ieee `gamma' function gives wrong results (at least for
47 [ *] The libm-ieee `scalb' function gives wrong results for
48 non-integral second parameters.
50 [ *] Collation symbol and equivalence class handling in regex are not
52 - [. .] at end of a range does not work
53 - [. .] and [= =] do not handle collating symbols (where a symbol
54 stands for multiple character) and multibyte character in
55 general not correctly.
57 This is *extremely* hard to fix since regex has to be rewritten
60 [ *] The regex implementation has various other problems, like limitations
61 of the expression size etc. [PR libc/1570, PR libc/1777]
63 None of these can be fixed without a rewrite.
