[Boost-users] [multi_array] Assertion when resizing empty array

Resizing an empty array no longer seems to work. My code worked fine with boost 1.38, now it causes an assertion with the latest boost trunk from svn. The code is: #include int main( int argc, char * argv[] ) { boost::multi_array< double, 2 > a; a.resize( boost::extents[2][3] ); return 0; } The assertion is: multi_array_resize: /home/john/Dev/ThirdParty/boost/boost-trunk/boost/multi_array/base.hpp:446: ArrayRef boost::detail::multi_array::multi_array_impl_base::generate_array_view(boost::type<Reference>, const boost::detail::multi_array::index_gen&, const typename boost::detail::multi_array::associated_types

::size_type*, const typename boost::detail::multi_array::associated_types, int NDims = 2, TPtr = double*, T = double, long unsigned int NumDims = 2ul]: Assertion `index_bases[n] <= start && start < index_bases[n]+index(extents[n])' failed. Aborted

My compiler is: john@john-dell:~/Dev/MyProjects/Bio/hmm$ gcc -v Using built-in specs. Target: x86_64-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.3.3-5ubuntu4' --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu Thread model: posix gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) I updated from svn today. I think the code creates a view on the old data in order to retain it. The assertion happens because this view is empty. Regards, John.
