c4_Bytes destructor causes memory deallocation failure

Hi,

I have another problem with c4_Bytes. It seems that
the destructor in some cases deletes the wrong memory.

The following code works as release build, but as 
debug build it fails in _CrtIsValidHeapPointer.

Curiously enough it works correctly as long as the
length is <= 16?

#include "mk4.h"
#include <string>
#include <iostream>
using namespace std;

void main() {
	c4_Storage storage("datafile.kit", true);
	c4_View v = storage.GetAs("v[b:B]");

	v.Add(c4_Row());
	c4_BytesProp pBytes("b");

	string teststring("Hello, this is a test!"); //
len=22
	c4_Bytes textbytes(teststring.data(),
teststring.length());

	pBytes(v[0]).Modify(textbytes, 0, textbytes.Size());

	// Works with up-to len=16
	c4_Bytes newbytes = pBytes(v[0]).Access(0, 16);
	//cout << string((const char *)newbytes.Contents(),
newbytes.Size()) << endl;

	newbytes = pBytes(v[0]).Access(0, 17);
	//cout << string((const char *)newbytes.Contents(),
newbytes.Size()) << endl;
}

Best Regards,
