Here on: GNU brebis 0.9 GNU-Mach 1.8+git20201129-486/Hurd-0.9 i686-AT386 GNU
I get:

So it is in:
STATIC void controlline(void)
{
/* Copy a compiler control line */
register int l;
register FILE *f1, *f2;

    f1 = fact;
    f2 = fpars;
    l = getc(f1);
    assert(l == '\0');
    do
    {
            l = getc(f1);
            if (l == EOF)
                    fatal(0, "temp file mangled", NULL );
            putc(l, f2);
    } while (l != '\n');

}

Maybe this is related to Hurd... I don't really understand what this is.
