IBM IDS ENTRP E / 5724L2304 / B15 - IDS 11.50

This problem will corrupt memory and can cause a segv or an 
assert failure to the engine. 
If the LAST COMMITTED option is used with the following query 
the engine will crash with 
various assertion failures. 
 
  set isolation to dirty read; 
  set lock mode to wait; 
  set PDQPRIORITY 10; 
  select max(col2) from customer; 
 
Here are two examples: 
 
oninit :: mt_shm_free_pool 
oninit :: destroy_session 
oninit :: sq_exit 
oninit :: sqmain 
oninit :: listen_verify 
oninit :: spawn_thread 
oninit :: startup 
 
oninit :: gather_records 
oninit :: rsread 
oninit :: fmread 
oninit :: readseq 
oninit :: gettupl 
oninit :: scan_next 
oninit :: producer_thread 
oninit :: startup
