   @vhexl -- I assume you're talking about the unity_memory files in extras? By non-symmetric, are you suggesting that instead of verifying the answer is zero at the end of each test, you have the option to specify a number of mallocs / frees that occurred, or something like that?

   Yes, I meant ./extras/unity_memory, I tried using this extra to test some memory issues with queues, for queues malloc and free were not always symmetric, causing heap_index to not be 0, and I had to set a large UNITY_INTERNAL_HEAP_SIZE_BYTES size to make malloc work.

   My code has an interface like this to use unity_malloc and unity_free

   void *_port_malloc(size_t s)
   {
       return unity_malloc(s);
   }
   void _port_free(void *p)
   {
       unity_free(p);
   }

   About heap_index
   

   Unity/extras/memory/src/unity_memory.c

   Line 45 in ce122c4

   static size_t heap_index;

   By the way, maybe "heap_index" can be used as a heap memory "water mark"
