xbacktrace will not give you any useful information when the crash is
inside redisplay, at least not normally, because redisplay is not
normally triggered by Lisp code. Redisplay is what Emacs normally
does when it is idle (on the C level).

Is this optimized build or unoptimized one? If the former, please try
reproducing the crashes with unoptimized builds. If this is already
unoptimized, please see what part(s) of the `it' structure caused the
crash, and show here their value(s).
If your xdisp.c is current, and assuming that this is an unoptimized
build (and so the backtrace is trustworthy), the problem seems to be
with trying to display something based on some string, which is stored
at it->string. Could you please see what string is that, and what is
its contents? That might give us a clue about whodunit.
