After a couple of hours I gave up. I tried greping for "build.*finally",
finally, build_destructor, destructor. I tried breaking in gimplify_expr but I
think it is already too late. I tried breaking in build_cleanup and
build_delete but those functions get called too often, and I didn't see where
the finally block is generated.

If someone knows exactly where the finally block is generated in the C++ FE,
please let me know, and I may give it another try in the future.
