ls -l ./usr/sys/ken/malloc.c
-rw-r--r-- 1 ken ken 1119 Nov 27 1974 ./usr/sys/ken/malloc.c

I found it in V5 also.

The comment in that file is not the same and some whitespace differs but
it is the same code.

This is 30 year old source code!

Found the V5 source code in its entirety:

Near exact match to 30 year old source code in V5:
http://minnie.tuhs.org/UnixTree/V5/usr/sys/ken/malloc.c.html

What the heck is SCO doing, claiming 30 year old source code as their own?

Hmm, you're right. In my Jan 2002 copy of the tuhs.org site I found PDP-11/Distributions/research/Dennis_v5/v5root.tar.gz, which contains this /usr/sys/ken/malloc.c:

        char *m_size;

struct map *mp;   
{   
        register int a;   
        register struct map *bp;   
   
        for (bp = mp; bp->m_size; bp++) {   
                if (bp->m_size >= size) {   
                        a = bp->m_addr;   
                        bp->m_addr =+ size;   
                        if ((bp->m_size =- size) == 0)

Note that because this has the advertising clause, it's actually GPL incompatible.

This isn't really relavant to the current issue, but how can they put a
2002 copyright date on a file which was not changed since written and
published in 1973? The file even contains the original 1973 copyright
notice.

Seems like an invalid copyright extension to me.

"nsys" code, Aug 1973, dating between v3 and v4.
http://minnie.tuhs.org/UnixTree/Nsys/sys/nsys/dmr/malloc.c.html

The v6 code (May 1975) is where these comments are introduced.
