I was using the current source on paris to build this, so it
is a bug in all our code I would guess.
I was using saber to try to figure out how more did something, and ran
across this:
"/source/4.3/ucb/more/more.c":761, tailequ(), Dereference (Error #67)
760: while (tail >= path)
* 761: if (*(--tail) == '/')
762: break;
------------------------------------------------------------
listing of: "/source/4.3/ucb/more/more.c"
755: register char *string;
756: {
757: register char *tail;
758:
759: tail = path + strlen(path);
760: while (tail >= path)
761: if (*(--tail) == '/')
762: break;
763: ++tail;
764: while (*tail++ == *string++)
765: if (*tail == '\0')
------------------------------------------------------------
(break 1) 30 -> path;
(char *) 0x12fb20 "a.out"
(break 1) 31 -> tail;
(char *) 0x12fb1f /* before start of: <data> */
------------------------------------------------------------
Saber is right of course, I will let the "experts" find the correct
fix for this. But I am surprised that the RT's don't die on this.
