| |
| 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://sourceware.org/bugzilla/ |
| |
| 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. |

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