Reproduction steps:

1. Check out the wip/testing-solidity-tests-wtih-hardhat branch of NomicFoundation/edr.
2. Check out the wip/solidity-test-merged branch of NomicFoundation/hardhat
3. Go to v-next/hardhat of the Hardhat checkout
4. Build Hardhat with pnpm build
5. Go to crates/edr_solidity_tests/tests/testdata of the EDR checkout
6. Link Hardhat with npm link $PATH_TO_HARDHAT/v-next/hardhat
7. Replace the value of https://github.com/NomicFoundation/edr/blob/wip/testing-solidity-tests-wtih-hardhat/crates/edr_solidity_tests/tests/testdata/hardhat.config.js#L4 with ["default/fuzz", "multi-version"] or ["default/repros", "multi-version"].
8. Run solidity tests with npx hardhat3 test:solidity

@agostbiro Can i try this issue?

[agostbiro]

Sure thanks @iosh . I might have actually fixed this already in https://github.com/NomicFoundation/edr/pull/716. Could you test it out by merging the latest feat/solidity-tests into your fork's wip/testing-solidity-tests-wtih-hardhat?

Sure thanks @iosh . I might have actually fixed this already in #716. Could you test it out by merging the latest feat/solidity-tests into your fork's wip/testing-solidity-tests-wtih-hardhat?

Ok , I will follow the steps to test and verify this issue.

[iosh]

@agostbiro I merged your change into the branch and the panic is resolved， When i run the npx hardhat3 test:solidity i see some tests fail， but i think the panic problem is resolved， should is submit a PR(your changes) to the wip/testing-solidity-tests-with-hardhat branch, or should just close this issue?

[agostbiro]

Awesome thanks @iosh ! I think it's expected that some tests fail there. We can close this issue.
