[Sdcc-user] malloc() on 64kB system only able to allocate ~ 1kB

[Duncan B. <dhg...@fa...>]

Hi,

I've just started using SDCC, compiling for the Amstrad CPC 464 (Z80
CPU, 64kB RAM).

The following code:

  void *block = (void*)0;
  long size = 0;

  while (1)
    {
      size += 128;
      block = malloc(size);
      if (block == (void*)0)
	{
	  printf("done\r\n");
	  break;
	}
      else
	{
	  printf("%ld\r\n", size);
	  free(block);
	}
    }

... is only ever able to malloc() 896 bytes, producing the following
output:

128
256
384
512
640
768
896
done
