Saxon » Saxon-CE

There's a special path in the code to handle the ranges a-z and A-Z in the code for case-independent matching, so the symptoms aren't quite as weird as they may seem. (See RECompiler lines 612-616)

However, the same code appears to be present in the 9.5 branch and the problem doesn't occur there.

This is a bug which has at some stage been fixed in 9.5 but not in Saxon-CE. In class IntRangeSet, lines 342-343 read

                System.arraycopy(startPoints, i, startPoints, i+1, used-i);

                System.arraycopy(endPoints, i, endPoints, i+1, used-i);

which on the 9.5 branch has been corrected to:

                System.arraycopy(startPoints, i, startPoints, i+1, used-i-1);

                System.arraycopy(endPoints, i, endPoints, i+1, used-i-1);
