Un objet classe n'est pas autoris? dans les unions.

Au niveau de la documentation :(IBM XL C/C++ for Linux, V12.1)
anonunion | noanonunion
Controls the members that are allowed in anonymous unions. When the
default, -qlanglvl=anonunion, is in effect, anonymous unions can have
members of all types that standard C++ allows in non-anonymous unions. For
example, non-data members, such as structures, typedefs, and enumerations
are allowed. Member functions, virtual functions, or objects of classes that have
non-trivial default constructors, copy constructors, or destructors cannot be
members of a union, regardless of the setting of this option.
This is an extension to standard C++ and gives behavior that is designed to be
compatible with previous versions of VisualAge? C++ and predecessor
products, and Microsoft Visual C++. Specify -qlanglvl=noanonunion for
compliance with standard C++.

La commande de compilation utilis?e:
xlc++ -q64 (en mode 64)
Les options test?s:
? -qlanglvl=anonunion
? -qlanglvl=noanonunion
? -qlanglvl=extended0x
Le message d'erreur par rapport ? l'exemple :

"union.C", line 13.9: 1540-1136 (S) "Point p" cannot be a union member, because "Point" has a non-trivial constructor.

    Hi, the provided test case now compiles clean with XL C/C++ for Linux, V16.1 using the following command:
    $xlc++ test.cpp -qlanglvl=extended0x
    $

    Marking the RFE as delivered based on the above. If any additional work is required, feel free to open a new RFE.
