CReduce originally created a radically reduced test-case which however was no
valid C++ anymore. (My check script was not specific enough.) It always failed
and should probably become another bug-report.
Radically reduced invalid C++ test-case:
----------------------------------------
namespace mpl_
}
namespace boost namespace mpl using namespace mpl_
}
}
namespace mpl_ template <T> struct integral_c;
}
namespace boost template <val> struct mpl::integral_c {
However, I was able to adjust it slightly. (I am not sure if this is really
valid C++14 code.)
Radically reduced (valid?) C++ test-case:
-----------------------------------------
namespace mpl_ {}
namespace boost { namespace mpl { using namespace mpl_; } }
namespace mpl_ { template <typename T> struct integral_c; }
namespace boost { template <typename val> struct mpl::integral_c {}; }
Both fail like this:
The error:
