Summary: studio hung with duplicate layer active
Initial Comment:
I don't know how I did it, but studio hung.
gdb shows me 2 threads both stopped, waiting to get a WriteLock:
#1 synfig::RWLock::writer_lock (this=0x325ac48) at mutex.cpp:204
#2 WriterLock (this=0x4286ba80, x...@0x325ac48) at mutex.h:98
#3 synfig::Context::set_time (this=0x4286bc50, time={value_ = 1}) at
context.cpp:342
#4 synfig::Layer_Duplicate::accelerated_render (this=0x325abb0, ...) at
layer_duplicate.cpp:181
#1 synfig::RWLock::writer_lock (this=0x32349d8) at mutex.cpp:204
#2 WriterLock (this=0x7fffdcf43d10, x...@0x32349d8) at mutex.h:98
#3 synfig::Context::set_time (this=0x7fffdcf43d70, time={value_ = 0}) at
context.cpp:342
#4 synfig::Canvas::set_time (this=0x3233f70, t={value_ = 0}) at canvas.cpp:299
#5 studio::CanvasView::rebuild_ducks (this=0x3252000) at canvasview.cpp:2916
#6 sigc::bound_mem_functor0<void, studio::CanvasView>::operator()
(this=0x35dfc00)
I was looking at the attached file - note it has a Duplicate layer. I suspect
the Duplicate code isn't taking care when calling 'set_time()'
