  Within the data blocks of the FDC record, there are references
  to an EFAULT signal ("Bad address") being returned by the
  operating system.
  

Local fix

• Change the application or queue manager configuration to use
  shared bindings
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of MQ applications which connect using
  isolated bindings and perform MQPUT
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A programming error meant that when passing an MQPUT request
  from an MQ application to the queue manager using isolated
  bindings, it was possible for uninitialized data to be passed to
  the operating system. If this uninitialized data was non-null,
  EFAULT was returned by the OS.
  

Problem conclusion

• The MQ isolated bindings logic, used by isolated bindings
  applications and the queue manager, has been corrected to
  prevent this use of uninitialized data.
