What steps will reproduce the bug?

Install necessary deps:

bun install graphql graphql-yoga@three

Create a test:

// segfault.spec.ts

import { it } from 'bun:test'
import { createYoga, createSchema } from 'graphql-yoga'

it('shouldnt segfault', async () => {
  const yoga = createYoga({
    schema: createSchema({
      typeDefs: /* GraphQL */ `
        type Query {
          hello: String!
        }
      `,
      resolvers: {
        Query: {
          hello: () => 'world',
        },
      },
    }),
  })

  const server = Bun.serve(yoga)

  // segfaults during fetch
  await fetch(
    `http://${server.hostname}:${server.port}/${yoga.graphqlEndpoint}`,
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        query: '{ hello }',
      }),
    },
  )
})

Run tests:

bun wiptest segfault.spec.ts

Output:

segfault.spec.ts:

Thank you for writing a test

So, I think this need to be checked again. Not sure if the issue is here or on the graphql-yoga repo

Bun version: 1.0.20
command: bun run src/bunApp.ts

import { createSchema, createYoga } from "graphql-yoga";

const yoga = createYoga({
  schema: createSchema({
    typeDefs: /* GraphQL */ `
      type Query {
        greetings: String
      }
    `,
    resolvers: {
      Query: {
        greetings: () => "Hello from Yoga in a Bun app!",
      },
    },
  }),
});
const server = Bun.serve({
  fetch: yoga,
});
console.info(
  `Server is running on ${new URL(
    yoga.graphqlEndpoint,
    `http://${server.hostname}:${server.port}`
  )}`
);

Both code blocks no longer crash and work normally.
