Hi Julian, I have seen something similar when writing tests for mappyfil. I've tried to find my test case in https://github.com/geographika/mappyfile/tree/master/tests but can't seem to locate it at the moment. I'm fairly sure I had some notes somewhere and it related to parsing MapServer expressions. I'll take another look later. Did you try to dump the Mapfile out using MapScript to see how it is stored internally in MapServer after it has been loaded?
