I've been running CURRENT with DEBUG_FLAGS=-ggdb in make.conf for a long time. It helps a *lot* when there is a core dump to have symbols in all the system libraries and binaries: root@kobe:/root# nm /bin/ls | grep ' [TDB] [[:alpha:]]' | head -3 08049760 T acccmp 0804e42c B ansi_bgcol 0804e400 B ansi_coloff ... I'm definitely in favor of making DEBUG_FLAGS=-ggdb on CURRENT and STABLE, but there's probably a small catch we have to consider: What to do about freebsd-update that crosses the boundary from -RELEASE to one of the -STABLE snapshots. If there are no hidden gotchas about running a system that is half-release/half-stable, then we should be fine. But it may be a good idea to update *all* the binaries at the crossing point, so that people don't have a base installation that only includes debug symbols for a small subset of the binaries.
