APAR status

  • Closed as program error.

Error description

  • A program loading the DB2 native libraries (e.g. a CLI
    program) may experience a SIGSEGV or SIGBUS crash if the
    application references a variable 'g_pTrace'. This is an
    internal global variable (i.e. reserved). It is not intended to
    be referenced by external applications.
    

Local fix

  • Do not define any application variables as 'g_ptrace'.
    
    To prevent further issues of this type, this variable will be
    renamed to decrease the potential for accidental reference.
