Package: libboost-dev
Version: 1.32.0-2
Severity: normal
When a multi_array rebasing to 1 is attempted via extent_range,
a segmentation fault happens on accessing the boundary element.
Workaround: use reindex. See the snippet below.
The 1.32.0-2 was built locally from the source package.
-- Transcript of a crash:
[EMAIL PROTECTED]:$ make t-boost-multiarray-reindex1

Segmentation fault
-- Test that causes the crash (t-boost-multiarray-reindex1.cpp):
#include <boost/multi_array.hpp>
int main()
{
typedef boost::multi_array<float, 1> arr;
float pi = 3.14;
#ifdef WORKAROUND
arr a(boost::extents[ 1 ]);
a.reindex(1);
#else
arr a(boost::extents[ arr::extent_range(1, 1) ]);
#endif
a[1] = pi;
return 0;
