APAR status

• Closed as program error.

Error description

• SQL_LOCAL_LEN and SQL_CODESET_LEN are too short on AIX. This
  causes memory corruption when used to calling DB2 APIs like
  db2CfgGet().
  

Local fix

• Instead of using:
  
  char territory[SQL_LOCALE_LEN+1] = "terr";
  char codeset[SQL_CODESET_LEN+1] = "codeset";
  
  Manually change the lengths to:
  
  char territory[33+1] = "terr";
  char codeset[17+1] = "codeset";
