Attached is a example piece that causes the crash.

If within the function and try to use the auto complete feature in the example within the function, the IDE will segfault when attempting to auto complete data within the union.

In my personal code, the segfault is happening as soon as I declare the structure. However if I give the structure with the attribute a name, the segfault does not occur (however this should not be required, since compilation can occur without).
