Thanks for reporting! I don't think it's severe enough to warrant a commit to -stable. Of course, if you want, you can manually apply the patches anyway to your tree. > The man man docs indicate that -a needs both a section and name, That's not what the manual page intends to say, "section" is still optional even with -a. I see how the text is confusing in this regard. It's also outright wrong because with -k, the command line may not even contain any name whatsoever, but -a still does its job. Jason, do you agree with the following patch? > but the segfault happens with either "n Tcl" or just "Tcl" past the -a. Yes, the section argument has nothing to do with it, it's not even required that the pages have the same name. But thanks for mentioning the confusing wording in the manual, too.
