<p class="MsoNormal">Hi Sean,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We experienced a crash of opensm in win8.<o:p></o:p></p>
<p class="MsoNormal">The core reason for the crash was that WinMad driver has not started for some reason.<o:p></o:p></p>
<p class="MsoNormal">So libibumad couldn’t work.<o:p></o:p></p>
<p class="MsoNormal">But it had a bug in error flow which caused an access violation.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I bring here two quotes of umad_open_port() function with my comments:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">// umad_open_port<o:p></o:p></p>
