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://sourceware.org/bugzilla/ + +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 [***] + +[ **] Closing shared objects in statically linked binaries most of the + times leads to crashes during the dlopen(). Hard to fix. + +[ **] The RPC code is not 64 bit clean. This is getting slowly fixed + but expect incompatible changes on 64 bit platforms like Alpha. + +[ *] 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 header file. In glibc it + is defined in which must not make the other + symbols in available. + [PR libc/140] + +[ *] The libm-ieee `gamma' function gives wrong results (at least for + -0.5). + +[ *] The libm-ieee `scalb' function gives wrong results for + non-integral second parameters. + +[ *] Several (most?) collation specifications are broken. The code which + is currently there is in most cases inherited from the originial + author (in case there is a LC_COLLATE specification in the locale + file) or is defined using the default (if iso14651_t1 is included). + + In any case we are missing information to correct the specification. + If you find the specification for your language be faulty please + send a report with instruction on what to fix. You don't have to + fix the specification yourself. + + The way it finally should look like (if the generic specification + is not correct) can be seen in the sv_SE file. Quite a few changes + on top of the generic specification can be made without duplication + of the whole LC_COLLATE description. + +[ *] Some of the functions which also handled IPv6 are currently broken. + IPv6 and IPv4 lookups occasionally happen when not needed. This + happens in getaddrinfo() and getnameinfo(). IPv4 handling of + these functions is OK though and there are patches available to fix + the IPv6 code as well. + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Ulrich Drepper +drepper@redhat.com -- cgit v1.2.3
