OK - so I found that just by wrapping my auto_ptr in an internal block 
inside the function, that the AV also goes away.

** This leads me to believe there is some sort of issue with unwinding the 
stack and destruction of the auto_ptr.

The problem function more closely looks like this:

//-- this version works fine
long __fastcall TObj::Func(AnsiString a,
                                          AnsiString b,
                                          AnsiString c,
                                          int d,
                                          long e /*= 0*/)
{
  try{
   std::auto_ptr<TLicenseMutexHandler>pLMH(new TLicenseMutexHandler(a));
    // do stuff to protected resource
  }__finally {  }
  return 0;
}



//-- this version crashes in the kernel - AV!
long __fastcall TObj::Func(AnsiString a,
                                          AnsiString b,
                                          AnsiString c,
                                          int d,
                                          long e /*= 0*/)
{
  std::auto_ptr<TLicenseMutexHandler>pLMH(new 
TLicenseMutexHandler(MainLFName));
  // do stuff to protected resource
  return 0;
}
