I have a reproducable crash on Windows XP with Python 2.7 which I would like to investigate. I have Visual Studio 2008 installed and I downloaded the pdb files. However I could not find any instructions on how to use them and was unsuccessful at getting anything out of it.

I checked the developer guide but could not find anything on debugging crashes. On internet, this seems to be also an underdocumented topic. So, a few questions : - is there some documentation to help debugging crashes ?

I don't think there is. As you say, it's somewhat underdocumented. Maybe someone else can point to something, but I'm not aware of anything.

- are the pdb files released along python usable with Visual Studio and stock Python ? Or do you need a hand-compiled version ?

I actually have no idea whether you drop in the .pdb files, but if you have VS anyway, it's easy enough to build and run within VS and let the debugger drop you into the code when it crashes.

Are you in a position to post a reproducible test case to the tracker? Or were you holding back until you'd done some analysis?
