--- Comment #2 from Jerry DeLisle <jvdelisle2 at gmail dot com> --- Well I do not know about how all the hooks work but this is with the following configure: ../trunk/configure --prefix=/home/jerry/dev/usr --enable-languages=c,c++,fortran --enable-libgomp --disable-bootstrap --enable-valgrind-annotations Enabling the valgrind annotations should give fairly accurate results. I do not know what you get on FreeBSD OS. I was using Fedora 40 OS.
