Its running time is proportional to the square of the total number of lines in its inputs, and it consumes memory roughly equivalent to the sum of the sizes of its input plus a nontrivial multiple of the total number of lines in its inputs. The best I can do is error out if the files are too large. -- You are receiving this mail because: You are the assignee for the bug.help
