bug(generator): Type Alias on byteslice causes generator to panic #158

Open itsdevbear opened 5 months ago

itsdevbear commented 5 months ago

for instance hexutil.Bytes from geth

Works:

    MyField []byte
}

Panics

import "github.com/ethereum/go-ethereum/common/hexutil"

type MyType struct {
    MyField []hexutil.Bytes
}

Can you share the sszgen script? I managed to run the generator with the testcases for this example here.

gsora commented 1 month ago

Hi, this issue is very much still present nowadays.

Minimum reproducer:

package main

type Int = uint256.Int

type Bug struct {
        Field *Int
}

go.mod:

module sszgen-bug

go 1.22.3

require github.com/holiman/uint256 v1.3.1

Run: sszgen -path .

Hi! Thank you for the example. I will take a look.
