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. | |
9 | ||
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 | |
12 | ||
13 | http://sourceware.org/bugzilla/ | |
14 | ||
15 | I would appreciate it very much if you could verify the problem was | |
16 | not reported before by looking through the database. Before reporting | |
17 | a bug please check the FAQ since it discusses also a lot of | |
18 | problematic situations. | |
19 | ||
20 | ||
21 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
22 | ||
23 | Severity: [ *] to [***] | |
24 | ||
25 | [ **] Closing shared objects in statically linked binaries most of the | |
26 | times leads to crashes during the dlopen(). Hard to fix. | |
27 | ||
28 | [ **] The RPC code is not 64 bit clean. This is getting slowly fixed | |
29 | but expect incompatible changes on 64 bit platforms like Alpha. | |
30 | ||
31 | [ *] The precision of the `sinhl' and/or `asinhl' function do not seem | |
32 | to be the best. | |
33 | ||
34 | [ *] On Linux, there should be a way to prevent defining the symbol | |
35 | NGROUPS_MAX in the <linux/limits.h> header file. In glibc it | |
36 | is defined in <posix1_lim.h> which must not make the other | |
37 | symbols in <linux/limits.h> available. | |
38 | [PR libc/140] | |
39 | ||
40 | [ *] The libm-ieee `gamma' function gives wrong results (at least for | |
41 | -0.5). | |
42 | ||
43 | [ *] The libm-ieee `scalb' function gives wrong results for | |
44 | non-integral second parameters. | |
45 | ||
46 | [ *] Several (most?) collation specifications are broken. The code which | |
47 | is currently there is in most cases inherited from the originial | |
48 | author (in case there is a LC_COLLATE specification in the locale | |
49 | file) or is defined using the default (if iso14651_t1 is included). | |
50 | ||
51 | In any case we are missing information to correct the specification. | |
52 | If you find the specification for your language be faulty please | |
53 | send a report with instruction on what to fix. You don't have to | |
54 | fix the specification yourself. | |
55 | ||
56 | The way it finally should look like (if the generic specification | |
57 | is not correct) can be seen in the sv_SE file. Quite a few changes | |
58 | on top of the generic specification can be made without duplication | |
59 | of the whole LC_COLLATE description. | |
60 | ||
61 | [ *] Some of the functions which also handled IPv6 are currently broken. | |
62 | IPv6 and IPv4 lookups occasionally happen when not needed. This | |
63 | happens in getaddrinfo() and getnameinfo(). IPv4 handling of | |
64 | these functions is OK though and there are patches available to fix | |
65 | the IPv6 code as well. | |
