I think it's a bit premature to ask debian-mentors for help when your RC 
bug is 7 minutes old. What you could do instead is:

* Wait a bit longer. Perhaps one of the numerous co-maintainers knows 
how to fix the bug, but they all busy or asleep at the moment?
* Ask on the team's mailing list.
* Ask upstream.

(Not necessarily in that order.)

The problem is that exp_flexer.cc was not regenerated from the 
corresponding *.ll file at build time. Instead, the file included in the 
.orig.tar (which was generated by an older flex) was used.

Removing the pre-generated flex output fixed it for me:

find -name '*.ll' | sed -e 's/[.]ll$/.cc/' | xargs rm
