Patching known bug in stl_algo.h in gcc 4.8.2 in trusty

[OpenFOAM]

There is a known bug in gcc 4.8.2 which needs fixing before we can compile and release our software OpenFOAM with Ubuntu 14.04. The bug and fix are reported here:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58800

To summarise, in include/bits/stl_algo.h, the change indicated by +/- is required in the following function:

  template<typename _RandomAccessIterator, typename _Compare>
    inline _RandomAccessIterator
    __unguarded_partition_pivot(_RandomAccessIterator __first,
     _RandomAccessIterator __last, _Compare __comp)
     {
       _RandomAccessIterator __mid = __first + (__last - __first) / 2;
- std::__move_median_to_first(__first, __first + 1, __mid, (__last - 2),
+ std::__move_median_to_first(__first, __first + 1, __mid, (__last - 1),
       __comp);
       return std::__unguarded_partition(__first + 1, __last, __first, __comp);
     }

Is it possible to fix this bug into an updated version of 4.8.2 on 14.04?

Thanks,

Chris

the upstream issue references an issue which was fixed upstream in October 2013. It is fixed in the gcc-4.8 package in trusty and utopic.
