Re: [Boost-users] Boost-users Digest, Vol 4538, Issue 1

17 Aug 2016

      Galvin,that was reported when boost version 61 was used, and the application was compiled with g++ version 5.21 with options 
CFLAGS += -fsanitize=alignment
CFLAGS += -fsanitize=object-size
CFLAGS += -fsanitize=vptr
Thanks, 
David.

Given that sp_counted_base is a base class of sp_counted_impl_p<>, I'm 
inclined to think that whatever is reporting that is confused.

It's also useless to make a post like this without specifying what 
version of Boost you are using and which tool is reporting these errors.

Please see the scenario below...am I doing something wrong or is this a gcc or multiprecision bug?

Thanks,

given the following code (multiPrecisionTest.cpp):

#include <boost/multiprecision/cpp_int.hpp>
#include <boost/multiprecision/cpp_bin_float.hpp>

typedef boost::multiprecision::int128_t int128_t;
typedef boost::multiprecision::cpp_bin_float_quad float128_t;

int main()
{
  int128_t intVal;
  float128_t floatVal(intVal.convert_to<float128_t>());

  return 0;
}

--------------------------------------------------------------------------

g++ -std=c++0x -c multiPrecisionTest.cpp
