What steps will reproduce the problem?
1. Parse the AST of strconv/atof.go with ast.MergePackageFiles(pkg,
ast.FilterFuncDuplicates)

What is the expected output?
The resulting AST contains:
func (d *decimal) atof32() (f float32, ok bool)
func atof32(s string) (f float32, err error)

What do you see instead?
The resulting AST is missing the decimal.atof32() decl and only has:
func atof32(s string) (f float32, err error)


Which compiler are you using (5g, 6g, 8g, gccgo)?
N/A

Which operating system are you using?
