Version mkgmap-r3796 was committed by gerd on Thu, 09 Feb 2017 ExpressionReader.patch for preventing a crash when two regular expressions are used but the 'and' or 'or' separating them is missing, for example: landuse=meadow & (name~'[Mm]eadow' name~'[Ff]ield') {delete name;} The existing code crashes. - Mike Baggaley http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3796
