Local fix

Problem summary

  • The effect on alternate UA instance is as if the script is never
    executed.
    

Problem conclusion

  • On Solaris, we found that calling putenv with a local char array
    would
    impact the ability of the Script DP to fork script child
    processes because of
    environment corruption in the parent UA process. We avoid this
    by using malloc'd
    storage in putenv calls.  To be safe, we've implemented this
    same logic on all
    UNIX/Linux platforms. Note that the problem has never been
    observed on Windows.
    
    The fix for this APAR is included in the following maintenance
