This is puzzling me... so I decided to check whether I could somehow reproduce
the problem here assuming your compiler derives from the one in System-III.
So, I have installed System III on SIMH from the tapes in TUHS. Silly me, I
didn't realize that I was using the ones for PDP-11 and so they are probably
farther from the WEGA than the tapes for VAX.
Still, while remaining within 16 bits, it seems like I can sort of reproduce
some similar behavior on the PDP-11 System-III. If I find some spare time I
will try to install SysIII on the VAX simulator as well and see if that works
better.
For the curious, I started off Hellwig Geisse's distro of V7 on PDP-11
http://homepages.fh-giessen.de/~hg53/pdp11-unix/
and succeeded to install mini-root. Then I had to use an intermediate V7
to restore from tape the tar archive of the full file system. After a few
extra changes, I got System III apparently up and running (at least reaches
single user and compiles itself).
I don't know if there is any additional interest on this, but should it be
I can make the UNIX System III distribution with instructions available for
anybody interested.
This distro comes with instructions AND a working system image, hence it
is big, much bigger than Geisse's V7, but for today's standards it is a
paltry 35M.
