Hi all,

I recently issued a system-update which went really bad. Most of the
builds were failing because lots of generic version symlinks in /usr/lib
were missing; I mean stuff like:
/usr/lib/libX11.so -> libX11.so.6

I pinpointed the problem to the generation of those symlinks which
apparently is done in a ./libtool script found in the source package for
a given program. (I haven't checked at which point this libtool script
is generated.) Well it happens that this step systematically fails here
when this ./libtool is run.
An example with flac that I've just cast: (note that it didn't make the
spell fail, while I'm now missing some symlinks to libFLAC.so)

from the compile log:

(cd /usr/lib && rm -f libFLAC.so.8 && ln -s libFLAC.so.8.2.0
libFLAC.so.8)
(cd /usr/lib && rm -f libFLAC.so.8 && ln -s libFLAC.so.8.2.0
libFLAC.so.8)
(cd /usr/lib && rm -f libFLAC.so.8 && ln -s libFLAC.so.8.2.0
libFLAC.so.8)
(cd /usr/lib && rm -f libFLAC.so && ln -s libFLAC.so.8.2.0 libFLAC.so)
../../libtool: line 5954: 31360 Segmentation fault      rm -f
libFLAC.so.8
(cd /usr/lib && rm -f libFLAC.so && ln -s libFLAC.so.8.2.0 libFLAC.so)
(cd /usr/lib && rm -f libFLAC.so && ln -s libFLAC.so.8.2.0 libFLAC.so)
../../libtool: line 5954: 31360 Segmentation fault      rm -f
libFLAC.so.8
../../libtool: line 5954: 31360 Segmentation fault      rm -f
libFLAC.so.8
../../libtool: line 5954: 31362 Segmentation fault      rm -f libFLAC.so
../../libtool: line 5954: 31362 Segmentation fault      rm -f libFLAC.so
../../libtool: line 5954: 31362 Segmentation fault      rm -f libFLAC.so

and now a glance at the code in ./libtool responsible for that:

if test "$#" -gt 0; then
        # Delete the old symlinks, and create new ones.
        for linkname
        do
                if test "$linkname" != "$realname"; then
                        $show "(cd $destdir && $rm $linkname && $LN_S 
$realname $linkname)"
                        $run eval "(cd $destdir && $rm $linkname && $LN_S 
$realname $linkname)"
                fi
        done
fi

Can anyone see what's wrong please?

Thanks,
Mathieu.
