Hi David,
That fix made fedora 20 happy. In one window did:
$ ./systemtap_write/install/bin/stap mmv.stp
instances: 0, 1
indom: 0
metrics: 0, 1, 2
In another ran the mmvdump from pcp:
$ ./mmvdump /proc/systemtap/stap_cb2f18a783870e1474713324d01a25f_25939/mmv
MMV file = /proc/systemtap/stap_cb2f18a783870e1474713324d01a25f_25939/mmv
