Yep, looks like a shell issue (which you can confirm by running
"crm_shadow -c name" by hand).

Looks like its segfaulting because CIB_shadow is not defined in the
environment (a side effect of "crm cib new" failing).
I'll fix the segfault, in the meantime, perhaps try "crm_shadow -c
name" and then run the crm commands as normal.
