//! Direct-mapping output adjustment shared by conformance harnesses.

/// Due to how Firedancer's VM CU accounting works, when
/// `virtual_address_space_adjustments` is enabled and execution fails with the
/// CU meter exhausted, we cannot compare the data region of the accounts with
/// Agave. Clears each supplied data buffer in that case.
