This becomes more and more stuff for a bug report, not for discussion

The old-italic script is defined in charscript.el, so check that file
for problems (damaged, truncated, outdated).  It is then used in
fontset.el, and the error you see comes from there, see the function
create-default-fontset.  Maybe by looking into these two files, or by
searching your system for outdated versions which shadow these, you
will find the culprit.

My next suggestion is to make sure the tree where you build Emacs is
clean, and doesn't contain any stale files from the previous versions
you've built.
