<p class="MsoNormal"><span style="color:#1F497D">No, Uri, you’re missing the point. How did you stop OpenSM? Was it immediately after it was started? Did you let it run for a fixed amount of time? The fact that it ran in your automated regression test environment
is worthless information – it is not actionable. You need to describe *<b>what</b>* your automated regression tests *<b>do</b>* allows someone to try to duplicate the problem, even if it’s one in 10000.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">I can’t believe that we have to argue about having repro steps included in bug reports. This is ridiculous. If you have a bug, tell whoever you are assigning the bug to how you ran into it. It really is not
that much to ask for.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Look, we all know you hate WinMad and WinVerbs, but please try to be a little more constructive in your interaction with Sean, Stan, and the community. The animosity is getting tiresome. I’d say the same thing
to Sean and Stan, and that was the main reason I responded – to let Leo know that the details in the bug report were good, unlike what Stan had suggested. However, I still stand by my statement that leaving repro steps out makes the bug report near worthless.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Leonid, there’s good detail in this report, but you’re missing a critical ‘repro steps’ section that would allow this to be reproduced and debugged by the bug owner. Just the crashdump information is only usually
enough for simple bugs, and your analysis is probably on the right track. Still, if you want someone else to look into it, it’s best to tell them how they too can see it – debugging things live is more productive than debugging by code inspection. How are
Sean or Stan supposed to test that they have indeed fixed a bug, assuming they find something suspect and make code changes, when they have no idea how you triggered it? Is it a consistent repro? 1 in a 100?<o:p></o:p></span></p>
