Describe the bug

I'm attempting to debug the challenges at https://github.com/RareSkills/huff-puzzles

The tests themselves run successfully, ie.:

❯ forge test --mc Add1Test
[⠢] Compiling...
No files changed, compilation skipped

Running 2 tests for test/Add1.t.sol:Add1Test
[PASS] testAdd1(uint256) (runs: 256, μ: 5417, ~: 5417)
[PASS] testNonMatchingSelector(bytes32) (runs: 256, μ: 5788, ~: 5788)
Test result: ok. 2 passed; 0 failed; 0 skipped; finished in 3.08s

Ran 1 test suites: 2 tests passed, 0 failed, 0 skipped (2 total tests)

But attempting to run the debugger on a function in the test file fails:

❯ forge test --debug testAdd1
[⠢] Compiling...
No files changed, compilation skipped
The application panicked (crashed).
Message:  index out of bounds: the len is 0 but the index is 0
