Because (TByteArrayList() << TMyStruct()) is not a temporary object, it's a
reference returned by operator<<
The temporary object is TByteArrayList() and that is bound to the reference
parameter of operator<< not to List, so as comment 1 says, the temporary does
not have its lifetime extended.
G++ is correct.
