thanks, that does the job after installing some valgrind-devel stuff. I apparently got stuck readings the description of --enable-checking, which also mentions valgrind, and then missed the relevant option. > If you don't bootstrap, be careful about compiler warnings as the > bootstrap compiler runs with -Werror in stage2 & 3. As long as I don't touch code outside fortran/libgfortran and watch new warnings, it is unlikely to break bootstrap for others. Thanks, Harald
