I see all segments when tracing e.g. /bin/sh

# procstat -v $$
  PID              START                END PRT  RES PRES REF SHD FLAG  TP PATH

How do I get memcheck-amd64-freebsd to run but stop before doing anything?

$ /usr/local/libexec/valgrind/memcheck-amd64-freebsd
valgrind: You cannot run '/usr/local/libexec/valgrind/memcheck-amd64-freebsd'
directly.
valgrind: You should use $prefix/bin/valgrind.
