--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-12-08 11:55:48 UTC --- Indeed, with 4.6.x preprocessed source for the reduced testcase this started failing with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=175158 aka PR43912. The only important difference at *.gimple level (except for renaming arguments and similar debug info only related changes) seems to be: -animate(F) [with F = std::function<void()>]::<lambda()> (const struct __lambda0 * this) +animate(F) [with F = std::function<void()>]::<lambda()> (const struct __lambda0 * __closure) { - const struct function * D.9363; + const struct function * D.9367; + const struct function * D.9368; + const struct function f [value-expr: __closure->__f]; - D.9363 = &this->__f; - std::function<void()>::operator() (D.9363); + try + { + D.9367 = &__closure->__f; + std::function<void()>::operator() (D.9367); + } + finally + { + D.9368 = &__closure->__f; + std::function<void()>::~function (D.9368); + } } so before this change __closure->__f wouldn't be destructed, now it is, and supposedly it is destructed in the caller too.
