Summary	07382: Hang and memory leak using save
Description	Might be an issue on other architectures as well.
Steps To Reproduce	1. [executable (e.g. mame64 if on 64-bit)] rdftu -d 2. save [filename],0xFFE00000,0x200000,0 3. The debugger, and thus MAME, will hang in an infinite loop as the length parameter is ignored, resulting in the address to copy being incremented infinitely. Out of bounds addresses are thus erroneously saved to [filename] (force quit MAME for this).

That would be bad. Try again with https://github.com/mamedev/mame/commit/cc52efc0958102124bfb965e5ba493153847f469
