I found this misbehaviour in several versions (3.0.12, 4b1 through 4b4):

if ("inf" == "inf") {
  print "OK";
}

if ("inf" != "inf") {
  print "BUG";
}

Comparing the string "inf" with itself (either literal or by variables) returns false,
and vice versa comparing with "!=" true. So far, "inf" is the only string with that
misbehaviour I've detected.
