<h3 id="hdr-Security">Security</h3> <p>This package is not designed to be hardened against adversarial inputs, and is outside the scope of <a href="https://go.dev/security/policy">https://go.dev/security/policy</a>. In particular, only basic validation is done when parsing object files. As such, care should be taken when parsing untrusted inputs, as parsing malformed files may consume significant resources, or cause panics. </p>     <h2 id="pkg-index">Index </h2>  <ul id="manual-nav">
