6 | This following list contains those bugs which I'm aware of. Please | |
bc9f6000 UD |
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. | |

bc9f6000 | 10 | Another source of information about bugs is the problem data base of the |
8f2ece69 | 11 | GNU project. There is an easy to use WWW interface available at |
bc9f6000 | 12 | |

15 | I would appreciate it very much if you could verify the problem was not | |
8f2ece69 UD |
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 | |
dfbad9c8 UD |
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 | |
20 | situations. | |

23 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
24 | ||
25 | Severity: [ *] to [***] | |
c57abfa7 | 26 | |
a673fbcb | 27 | [ **] Closing shared objects in statically linked binaries most of the |
5ad81f40 UD |
28 | times leads to crashes during the dlopen(). Hard to fix. |
29 | ||
4ad1f026 UD |
30 | [ **] The RPC code is not 64 bit clean. This is getting slowly fixed |
31 | but expect incompatible changes on 64 bit platforms like Alpha. | |
32 | ||
c57abfa7 UD |
33 | [ *] The precision of the `sinhl' and/or `asinhl' function do not seem |
34 | to be the best. | |
35 | ||
bc9f6000 UD |
36 | [ *] On Linux, there should be a way to prevent defining the symbol |
37 | NGROUPS_MAX in the <linux/limits.h> header file. In glibc it | |
38 | is defined in <posix1_lim.h> which must not make the other | |
39 | symbols in <linux/limits.h> available. | |
40 | [PR libc/140] | |
41 | ||
d111572f UD |
42 | [ *] The libm-ieee `gamma' function gives wrong results (at least for |
43 | -0.5). | |
44 | ||
45 | [ *] The libm-ieee `scalb' function gives wrong results for | |
46 | non-integral second parameters. | |
fe0ec73e | 47 | |
cf365734 UD |
48 | [ *] Several (most?) collation specifications are broken. The code which |
49 | is currently there is in most cases inherited from the originial | |
50 | author (in case there is a LC_COLLATE specification in the locale | |
51 | file) or is defined using the default (if iso14651_t1 is included). | |
52 | ||
53 | In any case we are missing information to correct the specification. | |
54 | If you find the specification for your language be faulty please | |
55 | send a report with instruction on what to fix. You don't have to | |
56 | fix the specification yourself. | |
57 | ||
58 | The way it finally should look like (if the generic specification | |
59 | is not correct) can be seen in the sv_SE file. Quite a few changes | |
60 | on top of the generic specification can be made without duplication | |
61 | of the whole LC_COLLATE description. | |
62 | ||
d3d99893 | 63 | [ *] Some of the functions which also handled IPv6 are currently broken. |
fdb7f386 UD |
64 | IPv6 and IPv4 lookups occasionally happen when not needed. This |
65 | happens in getaddrinfo() and getnameinfo(). IPv4 handling of | |
d3d99893 UD |
66 | these functions is OK though and there are patches available to fix |
67 | the IPv6 code as well. | |
