I realize it is, if you have a one-time non-reproducible failure. But if it happens more than once, you can install a -debug or -pdb package we'll provide with the pdb files, so that next time you can debug. Having in the same package means it's more comfortable to debug in general and also possible to debug hard-to-reproduce failures. Having them in a separate package means that users that do not need to debug, do not have to spend time/space/bandwidth to install them. So it's a tradeoff, not a pure yes/no question. </blockquote><div> </div><div>BTW, to get some numbers, I pushed it to our gerrit to have it built </div><div>by CI.
