emacs 22.1 on hp-ux 11.11 core dumps when DISPLAY not set

[Philippe Waroquiers <wao@cfmu.eurocontrol.int>]

In an hpterm (or in an xterm), emacs core dumps if DISPLAY is not set.
When DISPLAY is set, emacs startups properly.

(gdb) bt
#0  0xc020cc68 in kill () from /usr/lib/libc.2
#1  0x0013e6e8 in fatal_error_signal ()
#2  <signal handler called>
#3  0x00276d40 in _free_internal ()
#4  0x002778b0 in free ()
#5  0x001cef50 in emacs_blocked_free ()
#6  0x0027789c in free ()
#7  0x001ce564 in xfree ()
#8  0x000e4f00 in tty_default_color_capabilities ()
#9  0x000e5cac in term_init ()
#10 0x00040a84 in init_display ()
#11 0x0014042c in main ()
(gdb)

(note: bt full gives the same results, but with only some additional
error messages telling 'No symbol table info available.'.
xbacktrace command is not found).
