[aspect-devel] lexical_cast warning

[Timo Heister]

Hi Wolfgang,

my gcc 4.8.1 doesn't like lexical cast from double:

In file included from ../source/termination_criteria/end_time.cc:24:0:
/scratch/deal-trunk/installed/include/deal.II/bundled/boost/lexical_cast.hpp:
In instantiation of ‘bool
boost::detail::lexical_stream_limited_src<CharT, Traits,
RequiresStringbuffer>::shl_double(double, T*) [with T = char; CharT =

false]’:
/scratch/deal-trunk/installed/include/deal.II/bundled/boost/lexical_cast.hpp:1421:86:

                 finish = start + sprintf(out,"%.*lg",

I am tempted to replace this by 1e300 again. Thoughts?
