APAR status
Closed as program error.
Error description
Static constructor and destructor functions of classes defined in unnamed namespaces have their symbol names mangled using the name of the source file they are contained within. If multiple source files have the same filename, and same class/function names, the generated mangled names are identical to each other. When static initialization is performed, the functions can not be distinguished from each other, and the first matching function symbol from the first object file on the link line is used for each static init call.
Local fix
Rename source files with unique filenames.
Problem summary
PROBLEM DESCRIPTION: Incorrect function calls from unnamed namespaces due to non-unique mangled function names. USERS AFFECTED: Users with unnamed namespaces containing static constructors and destructors contained in source files with the same name.
Problem conclusion
The directory of the source file is now used to mangle the function name to distinguish between source files with the same name.
