   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.

  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://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl
  14
  15 I would appreciate it very much if you could verify the problem was not
  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
  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.

  25 Severity: [  *] to [***]
  26
  27
  28 [ **]  There are problems with signal handling when using LinuxThreads.
  29
  30 [  *]  The precision of the `sinhl' and/or `asinhl' function do not seem
  31        to be the best.
  32
  33 [  *]  The syslog function should print to the console if the LOG_CONS
  34        flag was given.
  35        [PR libc/72]
  36
  37 [  *]  On Linux, there should be a way to prevent defining the symbol
  38        NGROUPS_MAX in the <linux/limits.h> header file.  In glibc it
  39        is defined in <posix1_lim.h> which must not make the other
  40        symbols in <linux/limits.h> available.
  41        [PR libc/140]
  42
  43 [  *]  The localedef program should not generate errors if for categories
  44        which are not used for the output there are characters referenced
  45        which are not defined in the charmap.
  46        [PR libc/229]
  47
  48 [  *]  The rcmd() functions (more concrete: the handling of .rhosts) does
  49        not support netgroups and wildcards (+).
  50
  51 [  *]  When assembling a locale definition, that uses the "copy"
  52        directive, with localedef, not only the copied category is
  53        checked for errors, but the whole file containing the same
  54        category.
  55        [PR libc/207 and PR libc/454]
  56
  57 [  *]  The libm-ieee `gamma' function gives wrong results (at least for
  58        -0.5).
  59
  60 [  *]  The libm-ieee `scalb' function gives wrong results for
  61        non-integral second parameters.
  62
  63 [  *]  The *scanf() functions currently do not handle %l[ and %ls parameters
  64        correctly since the parsing of the multi-byte characters does not
  65        yet use mbsrtowcs().
