It is caused by the following test in lib/libnv/tests/dnv_tests.cc: ATF_REQUIRE_EQ(actual_val, NULL); In C++ mode, ATF_REQUIRE_EQ will attempt to output the value of NULL onto a std::ostringstream, but this has become ambiguous in C++11.  The fix is to cast the NULL value to the specific pointer type ATF is testing against, 'nvlist_t *' in this case. See the attached diff. -Dimitry  Before C++11, NULL is defined as 0, e.g. plain zero, and it will therefore be printed as an integer "0". In C++11 and later, NULL is defined as the keyword nullptr, e.g. the null pointer literal. Since the null pointer can be converted to any other pointer type, and there are many different operators defined in C++ to output those operators, the call is ambiguous, and must be resolved by the developer.
