      Trying to get some variables.
      Some pointers may be invalid and cause the dump to abort.
      Query (0x7f359a3565e8): p_l_c( NAME_CONST('p_BusinessDate',TIMESTAMP'2017-11-25 17:38:35'))
      Connection ID (thread ID): 78710
      Status: NOT_KILLED
      

      It is not clear how to reproduce, code of p_l_c() procedure (name changed) and several other related stored procedures can not be shared here.
