No, we cannot.
We don't have your symbols and your codes. You have to parse your dmp file with your symbols, and do the analysis.

Lecky, 
Did you really see it yourself first? It's just wasting every developer's time if you Lecky guys keep handling bugs like this. No matter POVB bugs or not.

Please stop using shared bugzilla account and don't ni me from now on. Please be responsible and sensible to bugs you report on bugzilla, and please do things make sense to analyze your bugs.

Wayne,
We really need certain actions to stop the people of Lecky from wasting developers' resources. This bug is not the first one during the past six months.
