This crash is consistently reproducible and it is crashing at the same place.

File : cairo-surface.c

Function :_cairo_surface_clone_similar

Line :  (*clone_out)->device_transform = src->device_transform;

I tried printing the 'device_transform' structure elements of *clone_out and
src with '%f' format just before the line where it crashes. As you can see
below, some of the structure values (like device_transform::xx,
device_transform::xy) of *clone_out are very large numbers.

The device_transform structure values for src
---------------------------------------------
src:device_transform::xx
=1.000000
src:device_transform::xy
=0.000000
src:device_transform::yx 
=0.000000 
src:device_transform::yy
=1.000000
src:device_transform::x0 
=0.000000 
src:device_transform::y0 
=0.000000

The device_transform structure values for *clone_out
---------------------------------------------------
*clone_out:device_transform::xx

clone_out:device_transform::y0

Please let me know if you need any further details. I appreciate your help to
investigate the root cause for the coredump.
