Unfortunatly, this build made me discover that my previous tests were'nt 
comprehensive enough

M-X shell makes emacs unresponsive (frozen)

configured with "--without-all --with-x-toolkit=lucid", 
CC=/usr/vac/bin/xlc_r  CFLAGS="-O3 -g"

Here's debugger backtrace after ^C:

Backtrace stopped: frame did not save the PC

Note: freeze happens also when not running under X11 (emacs -nw)

Going to try this with gcc now
