How to install debug symbols for corosync package on CentOS?

I got a crash in corosync which I would like to view in gdb. However, currently the core dump shows me only this much info Debug logs for core.1385 (Generated on Jul 26 10:17 BST) [Thread debugging using libthread_db enabled] Core was generated by `corosync -f'. Program terminated with signal 6, Aborted. #0 0x00007f68b2783495 in raise () from /lib64/libc.so.6 #0 0x00007f68b2783495 in raise () from /lib64/libc.so.6 #1 0x00007f68b2784c75 in abort () from /lib64/libc.so.6 #2 0x00007f68b277c60e in __assert_fail_base () from /lib64/libc.so.6 #3 0x00007f68b277c6d0 in __assert_fail () from /lib64/libc.so.6 #4 0x00007f68b3530f2c in ??

How to do this?
