Well, I'm open for a name-discussion anyway :)

That was from allocation.inline.hpp and is hidden behind an #ifdef 
ASSERT. the #elseif is

  return os::malloc(size, F, (caller_pc != 0 ? caller_pc : CALLER_PC));  ..

Also in thread.cpp there is no tracing, just an os:malloc:

      return throw_excpt? AllocateHeap(size, flags, CURRENT_PC)
-                       : os::malloc(size, flags, CURRENT_PC);
+                       : AllocateHeap(size, flags, CURRENT_PC,
AllocFailStrategy::RETURN_NULL);

So I wouldn't say that these os::malloc calls contain tracing...
