See http://dl.dropbox.com/u/1522424/Callgrind-JtR-DES-path-cropped.png
for an old version of JtR. Such graphs can be generated by building a
debug build of JtR and running it under Valgrind's callgrind tool (and
then seeing the output with kcachegrind). crk_password_loop is
indirectly calling format's DES_bs_cmp_one function (this might have
changed in the latest JtR).
However, I am unable to generate such graphs for latest JtR. I can
only see addresses of functions called in crk_password_loop. Has
anything changed in the Makefile which is leading to this behavior?

See crypt_all function in DES_fmt.c file (DES format's file).
