disabling test with precondition leads to error

[Patrick Moran <patrick.a.moran@…>]

Minimal reproduction:

#define BOOST_TEST_MODULE repro
#include <boost/test/unit_test.hpp>
BOOST_AUTO_TEST_CASE(fail, *boost::unit_test::precondition([](boost::unit_test::test_unit_id){ return false; })) {}

Output (1.60.0 from source):

Running 1 test case...

*** Errors were detected in the test module "repro"; see standard output for details

Based on the documentation here: http://www.boost.org/doc/libs/1_60_0/libs/test/doc/html/boost_test/tests_organization/enabling.html I assumed that disabling a test with a precondition was not supposed to be erroneous (the example had two tests fail, and one that did not run because of a failed precondition. Alltogether, two (not three) errors were reported. Also, the message indicates that we should look at stdout, but stdout has nothing.

• It doesn't require the predicate to be a lambda, that was just the shortest thing I could find for a small repro.
• It doesn't depend on this being the only test case - adding another case doesn't change the behaviour
