Whenever I attempt to search for a string using nano, it segfaults. I wasn’t sure if this was a bug in nano itself or a library it links to, so I built the latest version of nano from the source rpm provided on the upstream webpage. I tried a string search using the latest version, and it also segfaults in exactly the same way. This leads me to believe that one of the libraries that nano depends on is bugged, but I’m not sure which. Here is a gdb backtrace from the latest version of nano (2.2.1).
