  • Closed as program error.

Error description

  • The issue is that the compiler incorrectly generates "1586-475
    (W) New definition of function..." warning messges for files
    that have not changed since the PDF1 build step.
    
    If the source files have not been changed from the PDF1 build
    step, it should not issue the above warning on the PDF2 build
    step.
    

Local fix

  • N/A
    

Problem summary

  • USERS AFFECTED:
    Users with very large complex programs that make use of PDF1 and
    PDF2 compile time and link time options may be affected by this
    issue.
    
    PROBLEM DESCRIPTION:
    The algorithm that was used to map a specific funtion to a hash
    is incorrectly assigning multiple functions to the same hash
    name. As a result, the compiler may incorrectly produce a
    warning message for one of those functions if it wasn't changed;
    and if the other function was changed.
    

Problem conclusion

  • The compiler algorithm has been improved to reduce the number of
    hash collision; however, there may still be some occurances of
    these warnings (but not as many as before).
    

Temporary fix
