'Designated Inits' in CVI 2015 SP1

This document says that CVI 2015 support 'Designated Inits' with warning.

Using CVI 2015 SP1 this instruction

namespaceArray->value.dataSource = (UA_DataSource) {.handle = server, .read = readNamespaces,
                                                        .write = NULL};

doesn't give any warning and compiles fine, but while executing it produces a 'General Protection' fault.

I suspect this is related to the usage of 'Designated Inits' to set the members of UA_DataSource struct.

Could someone investigate this behavior?

You can see the error trying to run this example from open62541 library (OPC UA).
