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,

Rob Conde

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

That should work, as should:

float128_t f(intVal);

However, while both of these do work with msvc, they fail with GCC, so 
there is a bug (or 2) somewhere.  I'll investigate later.

Hi,

As I need a build of Python3 compatible with VS2012, I built it from
scratch and installed it in a _INSTALL folder, following a tutorial online.
Now, I want to use that Python3 with Boost.Python, so I did this in my
use-config.jam:
using python : 3.4 : D:/Tools/Python-3.4.5/_INSTALL/python.exe :
D:/Tools/Python-3.4.5/_INSTALL/include :
D:/Tools/Python-3.4.5/_INSTALL/libs ;

And then:

.\bootstrap.bat --with-python=D:\Tools\Python-3.4.5\_INSTALL
--with-python-version=3.4 --python-buildid=3
which failed.
The includes are found properly, but the link is floawed:

LINK : fatal error LNK1104: cannot open file 'python34.lib'

The library is in D:/Tools/Python-3.4.5/_INSTALL/libs, but could not be
found according to the log.
Also, something strange:
D:\Tools\boost_1_60_0\tools\build\src\engine>.\bootstrap\jam0 -f build.jam
--toolset=vc14 "--toolset-root=C:\Program Files (x86)\Microsoft Visual
Studio 14.0\Common7\Tools\..\..\VC\ "
--with-python=D:\Tools\Python-3.4.5\_INSTALL --with-python-version=3.4
--python-buildid=3

The retrieved toolset is wrong, as explicitely asked for VS2012 aka 11.0
int he user-config.jam and I'm running it from a VS2012 x64 native tools
command prompt.

Couldn't find any help online, so the best is to ask the Boost community!

Regards,

Matthieu
