That's right. This issue was reported quite a few times earlier in 
gluster-devel and it is not specific to gluster-nfs process. As updated 
in [1], we have raised bug1293594[2] against lib-gcc team to further 
investigate this.

As requested in [1], kindly upload the core in the bug along with bt 
taken with gcc debuginfo packages installed. Might help to get their 
attention and get a closure on this issue sooner.

Thanks,
Soumya
