delete causes crash with a character array

[Alex Vinokur]

GNU g++ 3.3.3, Cygwin


// Stuff

static char* mbuffer = NULL;

// Stuff

void doit()
{
  // Stuff
  mbuffer = new (nothrow) char [1001];
  assert (mbuffer != NULL);

  // Stuff

  assert (mbuffer != NULL);
  delete[] mbuffer;   // Sometimes crashed here (not always).
  mbuffer = NULL;

  // Stuff

}

How can one detect what causes the crash?

Are there any GNU utils that enable to help to solve the problem?
