> Has anyone gotten Compat_sunos to work, with any www-browser?

I use the SunOS Netscape 3.01 Gold binary daily, with no problems.
(Well, actually, every once in a while if I've downloaded a bunch of images
 over the course of using it, it'll do something which causes my R6 Xsun to
 try and realloc() some huge gob of memory, thus dying)

I'd use the SunOS 4.1.4 libraries; they work for me.

For reference, my /emul/sunos/usr/lib contains

I haven't made an /emul/sunos/usr/5lib; what programs are you using that
use that?  Surely not the SunOS "vi" ... a termlib/curses program, perhaps?

As for /dev/zero, if the system doesn't find /emul/sunos/dev/zero, it will
fall back to /dev/zero itself, which works ...

I've run 2.7beta5 without any problems like the one you report.  In practice,
I don't run Mosaic because it just doesn't support enough Netscape-isms, sigh.

This isn't getting very far, is it?

I can run both (under 1.2, not -current btw) without trouble.  I'd advise you
to get the SunOS 4.1.4 libraries first, then see if it dies in the same place.
Maybe the 4.1.2 ld.so is causing the problem.  It's not even getting far
enough to open() & mmap() libc.so ...
