Are there known problems building Emacs 18.55 for the SPARC {SLC} running
SunOS 4.1? Emacs immediately exits with a "Fatal error(6).Abort" caused
from line 515 of malloc.c, in malloc(). Tracing through it, it appears that
the first (?) malloc of a segment of 8 or fewer bytes results in p->mh_alloc
not ISFREE and p->mh_size not nunits. With HAVE_XWINDOWS and X11 defined,
this happens on the XOpenDisplay call in x11term.c, when the R4 Xlib
makes a copy of the displayname passed in; when built without X support
the same problem comes up in a different way. That problem does not manifest
itself with Saber-C 3.0, although that debugger doesn't like the
pointer subtraction in morecore() and later never loads the lisp files.
I have s-sunos4.h and m-sparc.h set by default; when I use s-bsd4-2.h instead,
temacs isn't built properly. This happens with both 'cc' and 'cc -misalign'
and with 'gcc -traditional' (gcc 1.37.1).
I've built this distribution for a DECstation and am pretty sure that my
procedure is correct.
I'm guessing that something in a crucial header file has changed, but I don't
know where to look. Has anyone got this working on a SunOS 4.1 machine?
Thanks very much in advance!
