Io does not work for the new gnu locale code on my system

[Peter Schmid]

Dear Mr Kosnick,

I have serious problems employing the new locale code on my system. My
system setup is vanilla SuSE 7.3 (Glibc 2.2.4, binutils 2.11.90.0.29)
running a 2.4.14 linux kernel.

1) I bootstrapped the compiler three times on different days. There
   are always massive io problems, reading does not work. Please
   confer the libstdc++ regression results.

Compiler version: 3.1 20011220 (experimental) 
Platform: i686-pc-linux-gnu
configure flags: --host=i686-pc-linux-gnu --enable-shared --disable-nls --enable-threads=posix --enable-clocale=gnu --enable-languages=c,c++,f77,objc
   
2) When I configure the libstdc++ library without any locale specific
   flags the generic locale code is chosen. From the information
   gleaned from the configure script I suppose on my linux box given
   the version of glibc the gnu version of the locale code should be chosen.

3) There is a core file generated by ./conftest in
   i686-pc-linux-gnu/libstdc++-v3 directory. Most probably generated by
   the locale specific test which seems to go wrong if no locale specific
   flags are specified.

4) IO does work for the generic locale abstraction. And additionally
   there are only three g++ compiler failures exposed by the g++
   regression testsuite. I believe these are irrelevant for the
   libstdc++ library.

Therefore, could it be that there is a subtle bug in the new gnu locale
code? The gnu locale abstraction worked as far io is concerned about
two weeks ago when I last bootstrapped the gcc 3.1 compiler before
the locale related changes went in.

Sorry, I had no luck debugging a failing program. Could you give me an
advise which version of gdb I should use for gcc 3.1?

Do I need a more recent copy of glibc or binutils for the new gnu
locale abstraction? 

Hope this helps,
