Well, the weirdnesses keep popping up as I write this program... :-)
Pike v7.8 release 473 running Hilfe v3.5 (Incremental Pike Frontend)
int z; sscanf("HOPP", "%*s%n", z);
(1) Result: 2
z;
(2) Result: 4
"HEJHOPP"[3..];
(3) Result: "HOPP"
sscanf("HEJHOPP"[3..], "%*s%n", z);
(4) Result: 2
z;
(5) Result: 7
Surely the result of sscanf("HOPP", ... should be the same regardless of how I compute the value "HOPP"?
