Gnu emacs 21.2 in HP-UX 11.11

[Tapani Tarvainen]

I have a strange problem with Gnu emacs 21.2 in HP-UX 11.11.

Specifically, whenever a buffer has shrunk so much that emacs
automatically disables auto-save, it freezes. Nothing short of
killing will have any effect.

The problem is specific to 21.2, it does not occur with 21.1
with exactly same configuration (built with identical commands
except different --prefix). The only unusual configure option
I use is --without-xim, and I'm using HP's ANSI C compiler.

It doesn't depend on any local initialization files, I tested
with -q --no-site-file. 
It does depend on X setup, or at least the problem doesn't
occur with -nw.

Suggestions, anyone?
