<a id="user-content-description-of-problem" class="anchor" href="#description-of-problem" aria-hidden="true"></a>Description of problem:</h2>
<p dir="auto">Currently we have <code>asn1_parser2tree()</code> which takes input from a given filename.
This requires <code>_asn1_yylex()</code> to do lot's of (buffered but slow) I/O. A function that takes a block of memory seems to be more elegant, less code and faster execution.</p>
<p dir="auto">Also, the current situation forces us to 'overwrite' <code>fopen()</code> when fuzzing <code>asn1_parser2tree()</code>. That introduces non-portable functions like <code>dlsym()</code> and <code>fmemopen()</code>. Regression testing the fuzz corpora as we do with <code>make check</code> has the same caveats. Thus the tests can't be run on every platform.</p>
