@bigfoot31 this issue is quite old now and we have tests to validate nested structures, would you mind check if this error happens with the newest version? If still happens, can you provide a complete code sample you are using?

It sill happens on the last tagged version and the master branch

package main

import (
	"github.com/jaswdr/faker"
)

type A struct {
	ChildrenType1 []*A
}

func main() {
	tmp := A{}
	faker.New().Struct().Fill(&tmp)
}

runtime: goroutine stack exceeds 1000000000-byte limit
runtime: sp=0xc020260408 stack=[0xc020260000, 0xc040260000]
fatal error: stack overflow

Tips : if you don't care about the field :

type A struct {
	ChildrenType1 []*A `fake:"skip"`
}

I'm taking a look on this
