initial crash under X on Irix or Solaris

[Dave Love]

This is compiled with SGI compiler 7.3.1.3m (which builds Emacs 21.3
OK) on Irix 6.5.22 in 32-bit mode.  Running ./emacs -q under X gives a
SEGV.  Gdb doesn't give a sensible stack trace and dbx just gives the
following.  Running in batch, e.g. to build leim, goes OK.

  $ dbx emacs
  dbx version 7.3.3 (78517_Dec16 MR) Dec 16 2001 07:45:22
  Executable /tmp/emacs/src/emacs
  (dbx) run -q
  Unable to correlate regions with rld, object listentry at address 0xfbe0418 
(length 12 bytes) cannot be read: not all in memory (prev entry object list 
address 0xfbe0418: object number 1)
  (dbx) 

On Solaris 9 I get an immediate segv under X.  With gcc (32-bit):

(gdb) r -q
Starting program: /var/tmp/emacs/src/emacs -q

Program received signal SIGSEGV, Segmentation fault.

With Sun C 5.6 I got a similar backtrace, but it crashed in cache_face.

Is no-one testing proprietary systems, even Solaris?
