Describe the bug

The erc4337-validation library leverages startDebugTraceRecording which requires increasing the verbosity to 3. (Otherwise you get vm.startDebugTraceRecording: no tracer initiated, consider adding -vvv flag error)

When setting verbosity to 3, it works fine. But when verbosity is increased to 4, it will panic.

To reproduce, clone the erc4337-validation repo, run installation and then run COLORBT_SHOW_HIDDEN=1 RUST_BACKTRACE=full forge test -vvvv and you will get:

Ran 1 test for test/SimulatorV060.t.sol:SimulatorTest
[PASS] testSimulate() (gas: 122480140)
The application panicked (crashed).
Message:  index out of bounds: the len is 0 but the index is 0
Location: /Users/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/revm-inspectors-0.12.0/src/tracing/writer.rs:368
