windows-specific functions like _aligned_malloc!), is working fine,

The heap-profiler has had a preliminary port to Windows. It has not
been well tested, and probably does not work at all when Frame Pointer
Optimization (FPO) is enabled -- that is, in release mode. The other

The heap-profiler has had a preliminary port to Windows but does not
build on Windows by default. It has not been well tested, and

such as the cpu-profiler and leak-checker, have not yet been ported to
Windows at all.
