Well, none could still mean glibc, which is all that is used now. I do not see a reason to strip out any glibc-based functionality on systems using it, unless a particular platform lacks those features. IIRC, the actual checks right now would be for dlfcn.h and execinfo.h. Eventually, the 'none' option would be for only those platforms that lack an equivalent native solution that requires no new dependencies. To be perfectly honestly, the actual reason we might gain nothing is that most distributions strip their binaries of debugging symbols, so not even GDB would be able to do much with them in the default case. There are usually ways around that, including rebuilding OpenOCD unstripped using the native package manager (e.g. Gentoo) or installing a separate package that contains the debugging information (e.g. OpenEmbedded, Debian). To be fair, these extra steps also moot my Heisenbug argument; however, these are still activities that could be expected by these platforms' users. Running GDB is not a user activity, except _possibly_ when using it _with_ OpenOCD. Remember, not everyone uses OpenOCD with GDB. I consider our "users" to include those developers who want to use OpenOCD as a replacement for an off-the-shelf tool. Such users do not want to be told to debug OpenOCD with GDB, but they might be convinced to install a debugging version of it (e.g. from Git). Too many users might give up when they hear that they need to run GDB to debug the feature that causes a crash for them. That goes for any package where They Just Wanted To Use It. As challenging as this work can be at times, they may give up for other reasons later anyway... why make bug reporting any harder for users than it absolutely needs to be?
