Another nonsensical backtrace.

func fromReturnStmt(fset *token.FileSet, info *types.Info, pos token.Pos, path []ast.Node, ret *ast.ReturnStmt) (*IfaceStubInfo, error) {
// Find return operand containing pos.
returnIdx := -1
for i, r := range ret.Results {

break
}
}
if returnIdx == -1 {
return nil, fmt.Errorf("pos %d not within return statement bounds: [%d-%d]", pos, ret.Pos(), ret.End())
}
concType, pointer := concreteType(ret.Results[returnIdx], info)
if concType == nil || concType.Obj().Pkg() == nil {
return nil, nil // result is not a named or *named or alias thereof
}
// Inv: the return is not a spread return,
// such as "return f()" where f() has tuple type.
conc := concType.Obj()
if conc.Parent() != conc.Pkg().Scope() {
return nil, fmt.Errorf("local type %q cannot be stubbed", conc.Name())
}
sig := typesutil.EnclosingSignature(path, info) // this is L0284
...
@prattmic Notice that all the lines matching L0284--the call to EnclosingSignature, which is not in the telemetry stack trace--are only loads from stack slots and the CALL itself: nothing really fallible.
