# Description Fixes a bug with `set_last_error()` introduced by @IanManske not being called during the jump to an error handler in IR eval. Without this, `$env.LAST_EXIT_CODE` wasn't getting set in the `catch` block for an external. # Tests + Formatting Added a `tests/eval` test to cover this in both IR and non-IR eval
