Define a class using std::mutex for when std::atomic<memory_resource*> cannot be used to implement the default memory resource.

2018-08-14Rope iterators: don't retain pointers when copiedredi
Rope iterators sometimes contain pointers to an internal buffer inside the iterator itself. When such an iterator is copied, the copy incorrectly retains pointers to the original. This patch takes the simple approach of not copying the cached information when the internal buffer is being used, instead requiring it to be recomputed when the copied iterator is dereferenced. An alternative would be to adjust the pointers so they refer to the buffer in the copy. 2018-08-14 Jeremy Sawicki <jeremy-gcc@sawicki.us> * include/ext/rope (_Rope_iterator_base(const _Rope_iterator_base&)) (_Rope_const_iterator::operator=(const _Rope_const_iterator&)) (_Rope_iterator::operator=(const _Rope_iterator&)): Ensure copied/assigned rope iterators don't retain pointers to the iterator they were copied/assigned from. * testsuite/ext/rope/7.cc: New. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@263534 138bc75d-0d04-0410-961f-82ee72b054a4
