Probably so, but at least I have a potential claim under fair use in that case, and (more importantly) I'm not subjecting Debian to legal liability. If you want it, great; let me know. > That's a pretty big leap from what we know so far, and at worst it > is local(remote) for the user running things they picked up on the > street (or maybe from the l337 'kitters at s*ny ;) Until we know > what it is about the data (if anything) that triggers this, its just > another bug to fix. All segfaults are bad. Well, yes, but I am just trying to keep on top of the potential issues. Not all developers are as up on security as you appear to be, so it was a general admonishment. I did look at the code after I sent the message, and it seems to be probably a bad pointer dereference to a single object, so nothing major. > > If you need more information, please feel free to let me know. > > Actually attaching the backtrace is probably a pretty good start ;-) Yes, I agree, and I could have sworn I did that. Oh, well. Note that it doesn't have debugging symbols, so it is probably of dubious value, although the function is a single line of code. When I tried with debugging symbols, I got another crash, but in a totally different place (and package). That doesn't inspire confidence... > I'm not sure what is likely to be done about this yet...
