[Debian-ha-maintainers] Bug#561755: Segfault in rgmanager

[Albert Sellarès]

Package: rgmanager
Version: 2.20081102-1

I got a segmentation fault with some cluster.conf files. My system is a
Debian Lenny with all latest updates. The problem is got with rgmanager
service and can be checked with rg_Test command.

I've attached a minimal cluster.conf to reproduce the problem.

root at debian:~/whats# rg_test test cluster.conf
