With the relevant section being:
public unsafe char[] ToCharArray (int startIndex, int length)
{
if (startIndex < 0)
throw new ArgumentOutOfRangeException
("startIndex", "< 0");
if (length < 0)
throw new ArgumentOutOfRangeException
("length", "< 0");
if (startIndex > this.length - length)
throw new ArgumentOutOfRangeException
("startIndex", "Must be greater than the length of the string.");
char[] tmp = new char [length];
fixed (char* dest = tmp, src = this)
CharCopy (dest, src + startIndex, length);
return tmp;
}
Which indicates new char [length] is returning NULL.
Before I trace this any further, is this something that's been seen before with
big arrays?
