OK, what version of xfsprogs?
If not latest usptream, please try that next.
If upstream still segfaults, you could provide a core and associated
binary debug info, or (maybe) an xfs_metadump for analysis. It sounds
like this fs is in pretty bad shape though, so even the xfs_metadump
might fail and/or not gather enough information.
