Right.  I think Walter meant that "new" would use the GC for allocation, so stubbing out gc_malloc() entirely will break "new".  I suggested replacing the GC with a non-collecting allocator, something like the malloc/free-based stub in Druntime.  Using this, "new" will work but you'll have to call "delete" to release the memory.
