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
#include
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());
return 0;
}
--------------------------------------------------------------------------
g++ -std=c++0x -c multiPrecisionTest.cpp
