DB2 - Problembeschreibung

Problem IT02973 Status: Geschlossen

ABEND IN SQLAK_CALLBDRDAINPUT DUE TO MISALIGNED MEMORY ACCESS, LEADING TO
SIGBUS SIGNAL

Produkt:
DB2 CONNECT / DB2CONNCT / A10 - DB2
Problembeschreibung:
A crash with a SIGBUS error in client side code may occur with 
the following stack : 
 
  sqlak_callbDrdaInput 
  sqljrGenSqlDta 
  sqljrDrdaArCall 
  sqleuInvokeActivationRoutine 
  sqleuPerformServerActivationCheck 
  sqleUCappConnect 
  CLI_sqlConnect 
  SQLConnect2 
 
The problems happens when DB2 accesses a 2 byte integer in a 
non-2 byte aligned location. 
Most platforms will handle this gracefully and perform a byte by 
byte copy instead in the kernel but in some cases , this signal 
may be passed to user code and trigger the SIGBUS signal causing 
a failure in the process.
