The relevant portion of shared_ptr_test seems to be n_report_2, reproduced below; it seems that the fault is occuring at the very first line of test(). I really can't see anything wrong with it; the test passes on every other platform. class foo { public: void setWeak(boost::shared_ptr<foo> s) { w = s; } private: boost::weak_ptr<foo> w; }; class deleter { public: deleter(): lock(0) { } ~deleter() { BOOST_TEST(lock == 0); } void operator() (foo * p) { ++lock; delete p; --lock; } private: int lock; }; void test() { boost::shared_ptr<foo> s(new foo, deleter()); s->setWeak(s); s.reset(); }
