No, that's too much pessimization. On top of that, it expose other compiler bugs. Just recompile the suspect binary and/or libraries with "-O0 -g" and install them seperately, like so: % cd /usr/src/lib/bind/isc % make cleandir; make cleandir % make obj % make depend % make DEBUG_FLAGS="-O0 -g" % sudo make install To find out which libraries a binary uses, do: % ldd /usr/bin/nslookup For code in the base system, I typically try to find a work-around so that we can compile with the default flags.
