Could not reproduce it on MSVC2010. Can you attach more info about this bug (backtrace, line number that triggers this error)

Replying to apolukhin:

Could not reproduce it on MSVC2010. Can you attach more info about this bug (backtrace, line number that triggers this error)

try it on MSVC2008. If you have this one.

compiler didn't find specialization for detail::lcast_src_length so sizeof(buf) is 2 bytes:

std::size_t const src_len = lcast_src_length::value;
char_type buf[src_len + 1]; // src_len equal 1 here

fix:

< typedef BOOST_DEDUCED_TYPENAME detail::array_to_pointer_decay<Source>::type src;
---
> typedef BOOST_DEDUCED_TYPENAME detail::array_to_pointer_decay<boost::remove_cv<Source>::type>::type src;
