I would like to bring attention to this bug. I'm surprised that although it was fixed nine months ago, the change did not make it to 1.54 beta1 or to trunk. Is that an oversight?

Example of what I expected was the removal of the unused variable current_char:

https://svn.boost.org/trac/boost/changeset/80797#file5

but what is found in 1.54 beta1 looks like this

http://svn.boost.org/svn/boost/trunk/boost/date_time/format_date_parser.hpp

version changed

Wed, 19 Jun 2013 11:25:05 GMT

version Boost 1.48.0 → Boost 1.54.0

To clarify (also selecting 1.54.0 as Version) that the issue is still found in

1.54 beta1
trunk
release branch

http://svn.boost.org/svn/boost/branches/release/boost/date_time/format_date_parser.hpp http://svn.boost.org/svn/boost/trunk/boost/date_time/format_date_parser.hpp

I have no explanation for this.

I made these changes; see [80699] (trunk) and [80797] (release), but the files in SVN no longer contain those changes.
