I've installed my packaged samba 4.5.5 on CentOS 7 and tried the upgrade
again.
Running the 'samba-tool domain classicupgrade' again fails with a silent
SIGSEGV.

[Samba] samba-tool domain classicupgrade smb_krb5_context_init_basic failed (Invalid argument)

Anyone?

My next concern is codepages. The latest source (I've moved to 4.5.5 now)
doesn't have any>> codepages. The RPM spec file I'm customising lists and wants to
install them here:
