List of known bugs (certainly very incomplete)
----------------------------------------------
Time-stamp: <1998-02-20T15:02:41-0800 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. Before reporting
a bug please check the FAQ since it discusses also a lot of problematic
situations.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Severity: [ *] to [***]
[ **] There are problems with signal handling when using LinuxThreads.
[ **] The libm-ieee `log2' function seems to be very inaccurate.
[ *] 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]
