> Where is the method being added and why are we not setting the access there? Are we creating it though `CreateFunctionTemplateDecl` should be be checking the `DeclContext` there to see if it is a `RecordDecl`?
We actually don't add it anywhere but instead use an already created related FunctionDecl and set this FunctionTemplateDecl as its specialisation (see `lldb/source/Plugins/SymbolFile/DWARF/DWARFASTParserClang.cpp:1216`).
We could also add the FunctionTemplateDecl to the DeclContext explicitly. That doesn't seem to break anything and seems consistent with the other functions for creating Decls. On the other hand I'm not sure if this is is some untested workaround for something.
But in any case, whatever we returned from this function (or whether it was added to the DeclContext) is in an invalid state that triggers an assert as soon as anyone calls getAccess on it.
