Hi All,
I've recently found a reproducible regression in Boost.Test while
moving from 1.32.0 to 1.33.1. This regression is apparently present in
the HEAD and 1.34 candidate as well.
I can confirm this problem (and the fix) on HP aC++ 06.12 (ia64), HP
aCC 03.67 (PA-RISC) and Sun Studio 11 (SPARC, with and without
-library=stlport4). According to one of our compiler vendors this is
reproducible on Tru64/Alpha cxx as well.
The fix is to change the test_unit::m_dependencies member (in
boost/test/unit_test_suite.hpp, unit_test_suite_impl.hpp in trunk)
from std::list<test_unit_id> to std::vector<test_unit_id> (yes, I know
that doesn't make a whole lot of sense).
The test case is:
---
#include <boost/test/included/unit_test_framework.hpp>
#include <boost/shared_ptr.hpp>
class DummyTest
: public boost::unit_test_framework::test_suite
{
public:
DummyTest() :
boost::unit_test_framework::test_suite( "DummyTest" ) {}
void testDummy() { BOOST_CHECK( true ); }
};
boost::unit_test_framework::test_suite *
init_unit_test_suite( int argc, char * argv[] )
{
boost::unit_test_framework::test_suite * test =
BOOST_TEST_SUITE( "Test Test Suite" );
boost::shared_ptr<DummyTest> suite_a( new DummyTest() );
test->add(
BOOST_CLASS_TEST_CASE( &DummyTest::testDummy, suite_a ) );
return test;
}
---
When the test has run, and once in global destructors, the binary
dumps core repeatably.
The stack trace of the crash is:

After applying the fix above the test runs reliably.
It'd be great to have this fix applied to the 1.34.0 candidate and the trunk.
