Hello. I opened a bug with nfs-utils on Redhat Bugzilla. And got an advice to email upstream. So I just repeat my bug text with a patch. How reproducible: always Steps to Reproduce: # mkdir -p /home/kudinae/Общедоступные # echo '/home/kudinae/Общедоступные oek-1(rw,sync,no_wdelay,no_root_squash,no_subtree_check)' > /etc/exports # exportfs -a Segmentation fault I've obtained the sources. So a crush happens on export.c:293. variable pos has negative value. I think problem into strtoint and export_hash functions. strtoint has unsigned type and always returns positive value but export_hash impicity cast it to signed int. So it is possible to get negative value. I wrote patch to fix this. Original Red Hat bug https://bugzilla.redhat.com/show_bug.cgi?id=863054
