Mir server crashed with SIGSEGV in mir::compositor::TemporaryBuffer::size() called from mir::gl::tessellate_renderable_into_rectangle() (LP: #1664760) .

Seg fault on detect_fd_leaks (LP: #1661498) -- Cemil Azizoglu <cemil.azizo...@canonical.com> Wed, 22 Mar 2017 04:54:19 +0000 ** Changed in: mir (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1664760 Title: Mir server crashed with SIGSEGV in mir::compositor::TemporaryBuffer::size() called from mir::gl::tessellate_renderable_into_rectangle() Status in Mir: Fix Committed Status in Mir 0.26 series: Fix Committed Status in mir package in Ubuntu: Fix Released Bug description: I run mir exempla: ./bin/mir_demo_server --launch-client ./bin/mir_demo_client_multistrea mir_demo_server crash when I move central animated object to right border and back. Cause of crash is to call size() function from invalid pointer in temporaty_buffers.cpp mc::TemporaryBuffer::size() - line: return buffer->size(); I have checked why pointer is invalid: In function: std::shared_ptr<mg::Buffer> mc::MultiMonitorArbiter::compositor_acquire(compositor::CompositorID id) from multi_monitor_arbiter.cpp auto& last_entry = onscreen_buffers.front(); last_entry.use_count++; if (mode == mc::MultiMonitorMode::multi_monitor_sync) clean_onscreen_buffers(lk); last_entry reference pointing not existing object (object is not longer in onscreen_buffers) after calling clean_onscreen_buffers() function. clean_onscreen_buffers() function looks correct for me - but after calling it, data remains inconsistent.
