<div dir="ltr">Sounds like an obj-c bug. The FieldDecl is probably actually an ObjCIvarDecl, and you probably want to use getContainingInterface() instead if it is.

Is FieldDecl::getParent() known to only be callable under certain circumstances (i.e., the plugin broken), or is something else broken?<br>
