   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://sourceware.org/bugzilla/
  14
  15 I would appreciate it very much if you could verify the problem was
  16 not reported before by looking through the database. Before reporting
  17 a bug please check the FAQ since it discusses also a lot of
  18 problematic situations.

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