I installed gabber (0.8.7.cvs20020712-6 in sid), and it works well
under LANG=ja_JP.eucJP locale with glibc 2.3.1-16.  When does the
gabber die?

Hmm, but if such major applications got the bug caused from glibc,
then we might get a lot of complaints.  I think your bug is not
glibc's.  At least we can't reproduce your bug if you don't do
anything...  If you're so busy, I close this bug for the present, and
wait another report like your problem.  Do you think about it?
