Yes, the interactive version had the wrong number of arguments on
an exec() function call. This has been fixed post 4.1. Here is PSmap.c
for the interactive version of ps.map. See how this compares with what you
have. (src.alpha/ps.map/ps.map/inter/PSmap.c)

#include <stdio.h>

PSmap(scriptfile, ps_outfile, background)
char *scriptfile, *ps_outfile;
int background;
{
    char input[1024],
         output[1024];

    sprintf(input, "input=%s", scriptfile);
    sprintf(output, "output=%s", ps_outfile);
    if (background && (G_fork() > 0)) exit(0);
    execlp("ps.map", "ps.map", input, output, 0);
    G_fatal_error("unable to exec ps.map");
}
