A crash in a gnus group with indic script in content and headers

[Manoj Srivastava]

Hi,

        I see these crashes frequently in indian mailing lists via
 gmane -- English language mailing lists (probably because of some indic
 language content -- I have to delete the messages, usually).

        I think this is a configuration option, since the emacs-snapshot
 package is not affected. I compile with:
--8<---------------cut here---------------start------------->8---
test ! -e Makefile || make maintainer-clean
../emacs/configure --with-x-toolkit=gtk --with-dbus --with-gpm           \
  --with-pop=yes --with-xpm --with-jpeg --with-tiff --with-gif --with-png\
    --with-x --with-xft --with-freetype --with-rsvg --with-libotf 
make bootstrap
--8<---------------cut here---------------end--------------->8---

        This is from the newsgroup:
  `nntp+news.gmane.org:gmane.user-groups.linux.mumbai'. The gdb trace is
  below.

        Should I try a run compiled with --no-opt?
