APAR status
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).
