SIGSEGV seen in /usr/sbin/fsck.hfs
On recent sid I am seeing a segfault with the hfsutils :
$ uname -a
Linux enceladus 5.6.0-1-powerpc64 #1 SMP Debian 5.6.7-1 (2020-04-29)

dmesg claims :

This was a bit of a surprise. I went looking for the sources to hfsutils
and see that it has been slightly revised since 1998 but is largely the
same as it has been for a long long while. Not sure what the SIGSEGV is
being caused by and I think I will wipe the machine and install with the
netinst from 2020-05-30 and hope that a re-partition of the disk and new
hfs boot file filesystem may be clean. Has anyone else seen issues with
the bootable hfs partition?
