crash in boost regex

Description
Using a specific search and replace expression containing named tags causes boost regex to crash. The pull request at https://github.com/boostorg/regex/pull/60/commits/124dd8d0d9c636436115ec988058a551c5fa39eb turns the crash into a regex exception. Attaching the search/replace expression and the file they are used on.

Attaching example.cc to show the problem. It looks like the crash is only happening if boost::u32regex is used. Using wide strings instead of strings makes the crash go away on OSX, but not on Windows. Both crash with regular strings.
A note to the pull request: it does not fix the problem, it just prevents boost from crashing.
