Hopefully it exhibits the same problem as you found; if so the issue > is fixed in git. A fix is always good, of course. However, I believe that my debug output showed that the problem occurs when $error is non-zero for the first time already. I should perhaps mention that this is happening within a function, and (I think) the lag order parameter should stay constant for each function call. So I believe the following sequence of events applies roughly: - function is executed, inside it we have "catch var..." working but not reacting because everything is perfectly valid - this happens many times, first because the "catch var" is also inside a loop, and secondly because the function is called repeatedly - then the same function is called with invalid lag order 0, and at the first loop iteration "catch var..." should set $error to non-zero. - But instead of executing the "if err ... endif" block correctly (and perhaps failing afterwards), I got the unpaired-if error.
