Pasting in Shyam's analysis so we can fix it:

> Problem is due to (2) below, but (1) also needs addressing I think.
>       
> Failed regression that Nigel pointed me to: https://build.gluster.org/job/regression-test-with-multiplex/438/console
> 
> 2 bugs:
> 1) this line https://github.com/gluster/glusterfs-patch-acceptance-tests/blob/master/regression.sh#L27 should have "set pagination off" as follows,
> 
> gdb -c <path to core> -q -ex "set pagination off" -ex "info sharedlibrary" -ex q 2>/dev/null
> 
> 2) this line https://github.com/gluster/glusterfs-patch-acceptance-tests/blob/master/regression.sh#L109 can be changed to:
> 
> gdb -ex 'core-file <path to core>' -ex 'set pagination off' -ex 'info proc exe' -ex q 2>/dev/null | tail -1
> 
> Alternative to the above would be to extract the executable name from,
file <corefile>, but I am not certain the output would be similar on all systems.
