Description Yves De Muyter 2014-10-18 08:22:10 UTC

Reproducible with the wayland clients/simple-egl application by simply
pressing 'esc' on the window (closes the window) or doing 'ctrl-c' on
the terminal. The result is a Weston crash.

What happens is that the buffer is set to NULL while still used.

See

for a fix.
