ARM and probably the rest of the arches have significant memory leaks as they have no release interface. Additionally, DrMemory does not have 64-bit support and thus I can't test the 64-bit version under Windows. Under Linux valgrind supports both 32-bit and 64-bit but there are different macros and code for Linux and Windows.
