Any hints/advice/guesses? seems that you are using two different allocators here. one is that comes with DLL and other that comes with D. i bet they either using different runtimes, or C runtime is doesn't know about another C runtime in DLL. on GNU/Linux there is only one runtime (most of the time), so there is no problem with different allocators.
