List of known bugs (certainly very incomplete) | |
---------------------------------------------- | |
Time-stamp: <1997-11-12T04:42:03+0100 drepper> | |
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. | |

Severity: [ *] to [***] | |
[ **] There are problems with signal handling when using LinuxThreads. | |
[ **] The libm-ieee `log2' function seems to be very inaccurate. | |
[ *] The libm-ieee `remquo' function rounds 3.0/2.0 incorrectly. | |
[ *] The precision of the `sinhl' and/or `asinhl' function do not seem | |
to be the best. | |
[ *] The syslog function should print to the console if the LOG_CONS | |
flag was given. | |
[PR libc/72] | |
[ *] 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 localedef program should not generate errors if for categories | |
which are not used for the output there are characters referenced | |
which are not defined in the charmap. | |
[PR libc/229] | |
[ *] The rcmd() functions (more concrete: the handling of .rhosts) does | |
not support netgroups and wildcards (+). | |
[ *] When assembling a locale definition, that uses the "copy" | |
directive, with localedef, not only the copied category is | |
checked for errors, but the whole file containing the same | |
category. | |
[PR libc/207] | |
[ *] The libm-ieee `asin' function gives wrong results (at least for 0.5). | |
[ *] _IO_getline can loop forever, at least with C++ | |
[PR libc/332] | |
