I started emacs with

emacs

and got the following error-message:

pid 13629 (emacs) was killed on an unaligned access, at pc 0x42bd40
Fatal error (10).Bus error(coredump)

I tried again:

emacs -q

and got

pid 13630 (emacs) was killed on an unaligned access, at pc 0x42bd40
Fatal error (10).Bus error(coredump)

An emacs window did not appear. The command

emacs -nw -q

worked well. Typing

M-x emacs-version RET

gives

GNU Emacs 19.25.1 of Mon Jul  4 1994 on bross3 (mips-dec-ultrix4.3)

I run emacs on a DECstation 5000/50 and get the start-message:
ULTRIX V4.3A (Rev. 146) System #2: Tue Dec 14 15:34:16 MET 1993
UWS V4.3A (Rev. 25)

I started configure with:

./configure --prefix=/dec240/emacs

The error occurs sometimes, and on another day emacs starts well
(But might cause a bus error occasionaly, e.g. if the shell output
is to large). Today I could start emacs only once (after 10 tries)
under X11.
Of course there my be a bug in the operating system or
hardware as well.
