font-lock.el has some `defsubst' (i.e. functions that get inlined) so the
backtrace is "incomplete".  The call to eval is actually in
font-lock-apply-highlight or in font-lock-fontify-anchored-keywords (both
inlined functions called from font-lock-fontify-keywords-region).

If you load font-lock.el (i.e. the source code), the backtrace will be
a lot more complete.
