Debugging page needs overhaul
It has been noted (by Patrick Storz, during the recent re-write of Report Bugs page, related to this bug report: https://bugs.launchpad.net/inkscape/+bug/1774404) that the Debugging page (https://inkscape.org/en/develop/debugging/) needs an overhaul. When the Report Bugs page was re-written, the info about GDB for Windows users was removed, since it's more relevant for advanced users (and the new Report Bugs page needs to target less tech-savvy users).
However, in the rare case where an intermediate user might need to provide the GDB info for bug fixers, these instructions should be available somewhere for them. And it seems the Debugging page is the most appropriate place.
So, in summary, overhaul of Debugging page is needed, and specifically it needs to include the GDB info for Windows users. This is not seen as an urgent need.
