Segmentation Fault when loading AMLLibraries companion specification

[keba-uso]

The issue appeared when loading the companion nodeset into the OPC UA server. The version of the UA-Nodeset tested:

• Repository: https://github.com/OPCFoundation/UA-Nodeset
• Branch: latest
• Commit: a2208e8

When testing with the latest version of the AMLLibraries companion nodeset with open62541 v1.3.2 I get a Segmentation Fault error:

Loading of the following nodes from the AMLLibraries results in termination of the whole program:

• ns=2;i=46
• ns=2;i=49
• ns=2;i=67
• ns=2;i=104
• ns=2;i=113
• ns=2;i=116
• ns=2;i=119
• ns=2;i=125
• ns=2;i=128

Here is the structure of one of the aforementioned nodes:

It is probably confusing for the actual XML parser when both the variable attribute (DataType="String") and the ExtensionObject DataType Identifier (<Identifier>String</Identifier>) define a type. After removing the attributes from the nodes with the following IDs, the nodes were loaded successfully.

But the Segmentation Fault error should definitely be resolved within the nodesetLoader implementation.
