Dangling pointers

Today I tried to install valgrind, but I discover that it works only on Linux. I tried for a while to put the linux working in the Mac, but it was bring more pain than gain, and I gave up. I discovered one bug in the phi deconstruction algorithm. It is very weird: the memory slot @0x8d29fdc is been overwritten by an operating that has nothing to do if that memory location. I wonder how many dangling pointers I have in the code...
