List of known bugs (certainly very incomplete)
----------------------------------------------
Time-stamp: <1998-03-14T09:23:56-0800 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.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Severity: [ *] to [***]
[ **] There are problems with signal handling when using LinuxThreads.
[ *] 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]
[ *] 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 and PR libc/454]
[ *] 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]
[ *] _IO_getline can loop forever, at least with C++
[PR libc/332] The problem is fixed for glibc 2.1.
[ *] The rcmd() functions (more concrete: the handling of .rhosts) does
not support netgroups and wildcards (+).
[ **] When popen() was called with an illegal command the function still
returns with a value not equal to NULL.
[ *] setlocale() leaks memory. This becomes only a problem if a program
calls this function very often which normally is not the case. The
problem is fixed for glibc 2.1.
[ *] Using the NSS modules from statically linked programs sometimes
fails (for very large entries). The problem is fixed in glibc 2.1.
