------- Comment #7 from singler at gcc dot gnu dot org 2009-10-20 07:46 ------- Sorry, the CC has never reached me. So concerning comment #4: Was the parallel mode actually activated? The multiway mergesort takes another time the space of the input as temporarily. Sure that the program was not swapping?
