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

Please try to debug it and find the cause.
First I suggest recompiling using -g.
(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).
That means the .gdbinit file wasn't found or didn't work.
Please try to figure out why.

.gdbinit was not found because I was not in the good directory.
After recompiling with debug and using gdb, I was able to see
what is happening, and tested a fix.
The problem is that when emacs starts up without DISPLAY, it calls
the function tty_default_color_capabilities.
For a reason not clear to me (my knowledge of C is *very* rusty),
the static local variables in tty_default_color_capabilities are
not properly initialized to NULL or 0 at startup.
I first tried to just put a " = NULL;" and a "= 0;"
but that did not solve the problem.
At the end, the problem was solved by moving the static variables
just before the function tty_default_color_capabilities
(and also initializing them to NULL/0).
In other words, the below fixes the problem:
/* Save or restore the default color-related capabilities of this
terminal. */
static char
*default_orig_pair, *default_set_foreground, *default_set_background
= NULL; /* need init ??? */
static int default_max_colors, default_max_pairs,
default_no_color_video = 0; /* need init ??? */
static void
tty_default_color_capabilities (save)
int save;
{
if (save)
{
if (default_orig_pair)
As I do not understand too much the problem, if you need any other
investigation, I can
always see what I can do.
Thanks for your help ...

I have done a test to see if emacs compiles and runs properly
when commenting the
#define static
line in s/hpux.h
I tested with the below versions of hp-ux and c compiler.
The emacs was properly configured/compiled with the below change
in hpux.h.
I started the resulting emacs on an X display and on a tty.
With this basic test, everything seems ok.
Conclusion: hpux 11.11 and the below version of the compiler
does not have a problem with the "static".
Hoping this helps ...

That is useful information -- thanks. To see what conclusions we can
draw from it, I need some more info:
Is HPUX 11.11 the current version?
How many years ago was HPUX 11.11
released?

According to the internet, it was released in 2000 and is 3 or 4
versions old.
I looked for non-file scope statics in src/*.c. I think there are only
a handful that aren't definitely in Windows, Mac, or VMS specific code:
grep -E '^[ \t]+static ' *.c | grep -Ev '^(w32|msdos|mac)'
alloca.c find_stack_direction
fringe.c init_fringe_bitmap
gtkutil.c menu_grab_callback, xg_separator_p
image.c our_memory_fill_input_buffer, gif_load
xselect.c x_reply_selection_request
Not relevant:
emacs.c (commment), getloadavg.c (vms), regex.c (not emacs),
strftime.c (indented file scope), sunfns.c, sysdep.c (vms), unexsunos4.c
