Description:
Populating NDB with 15M rows caused a crash in DBACC when committing the transaction.

The PK is a long key (48 bytes).

/* ******************---------------------------------------------------------------\
 */
/* ACC_CONTOPREQ                                        COMMIT  TRANSACTION         \
 */
/* ******************------------------------------+                                \
 */
/*   SENDER: LQH,    LEVEL B       */
void Dbacc::execACC_CONTOPREQ(Signal* signal)
{
  Uint32 tcorLocalFrag;

  jamEntry();
  lcpConnectptr.i = signal->theData[0];
  /* CONNECTION PTR                  */
  tcorLocalFrag = signal->theData[1];
  /* LOCAL FRAG ID                   */
  tresult = 0;
  ptrCheckGuard(lcpConnectptr, clcpConnectsize, lcpConnectrec);
  ndbrequire(lcpConnectptr.p->lcpstate == LCP_ACTIVE);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Fails here.

How to repeat:
Will get program that populates the db
