<pre>Recently I wanted to disassemble the text section of a mach-o binary. The text
section is almost 4 MB in size, but otool only disassembles the last 27 KB of
it. It starts disassembling at the first known symbol and as the binary was
heavily stripped and optimized, there were almost no symbols in the final
binary. I reported that bug to Apple and here is what they said:
<span class="quote">> Engineering has determined that this issue behaves as intended

So basically Apple points with the finger on you and says it's your fault.
Well, I am part of that community and wanted to let you know that this is
absolutely undesired behavior. I don't understand that behavior and I don't
want it either. Using otool-classic the whole section is disassembled which
saved my day but I don't want to reply that Apple will keep that one around for
ever.</pre>
