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:

   
#

struct map {   
        char *m_size;   
        char *m_addr;   
};   
   
malloc(mp, 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)   
                                do {   
                                        bp++;   
                                        (bp-1)->m_addr = bp->m_addr;   
                                } while ((bp-1)->m_size = bp->m_size);   
                        return(a);   
                }   
        }   
        return(0);   
}   
   
mfree(mp, size, aa)   
struct map *mp;   
{   
        register struct map *bp;   
        register int t;   
        register int a;   
   
        a = aa;   
        for (bp = mp; bp->m_addr<=a && bp->m_size!=0; bp++);   
        if (bp>mp && (bp-1)->m_addr+(bp-1)->m_size == a) {   
                (bp-1)->m_size =+ size;   
                if (a+size == bp->m_addr) {   
                        (bp-1)->m_size =+ bp->m_size;   
                        while (bp->m_size) {   
                                bp++;   
                                (bp-1)->m_addr = bp->m_addr;   
                                (bp-1)->m_size = bp->m_size;   
                        }   
                }   
        } else {   
                if (a+size == bp->m_addr && bp->m_size) {   
                        bp->m_addr =- size;   
                        bp->m_size =+ size;   
                } else if (size) do {   
                        t = bp->m_addr;   
                        bp->m_addr = a;   
                        a = t;   
                        t = bp->m_size;   
                        bp->m_size = size;   
                        bp++;   
                } while (size = t);   
        }   
}
