Bug#632938: g++-4.6: 4.6.1-2 broke boost::multi_array when compiling with -std=c++0x
Package: g++-4.6
Version: 4.6.1-2
Severity: normal
Hi,
with g++-4.6.1-1, the following program compiled fine with the -std=c++0x
command line switch:
#include <boost/multi_array.hpp>
int main() {
boost::multi_array<int, 3> x(boost::extents[1][2][3]);
}
Since g++-4.6.1-2, it doesn't compile any longer (it does compile with
-std=c++03).
The error message looks like this:
