Hi All.

We have the heterogeneous corosync/pacemaker cluster of 5 nodes: 3 SL7(Scientific linux) and 2 SL6.
SL7 pacemaker installed from a standard repo (corosync - 2.3.4, pacemaker - 1.1.13-10), SL6 build from sources (same version).
The cluster not unified, some nodes have RA which other do not have. crmsh used for management.
SL6 nodes runs surprisingly smoothly, but SL7 steady segfaulting in the exactly same place.
Here is an example:

Core was generated by `/usr/libexec/pacemaker/lrmd'.
Program terminated with signal 11, Segmentation fault.
