[LLVMbugs] Fix for heap corruption bug

[Argiris Kirtzidis]

Hi,

The attached patch fixes a very small bug:

---------------------------------------
  if (!cstr)
    cstr = new char[len + (isNullTerm ? 1 : 0)];
 
  assert (cstr != NULL);
 
  for (unsigned i = 0; i < len; ++i)
    cstr[i] = (char) ReadInt();
 
  if (isNullTerm)
    cstr[len+1] = '\0';
---------------------------------------

"cstr[len+1] = '\0';" writes one byte after the reserved block of 
memory; msvcrt was kind enough to report it with a "heap corruption" 
error ;)
