           Summary: cairo-path-stroke.c:1816:
                    _cairo_rectilinear_stroker_line_to: Assertion `a->x ==
                    b->x || a->y == b->y' failed.
           Product: cairo
           Version: 1.9.5
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: malte.nuhn at rwth-aachen.de

Trace that leads to the Assertion failure.

The given combination of commands leads to the following assertion failure:

lt-csi-replay: cairo-path-stroke.c:1816: _cairo_rectilinear_stroker_line_to:
Assertion `a->x == b->x || a->y == b->y' failed.

I noticed this by plotting a lot of small graphs, which basically only differ
in the y-coordinates. If this is really a problem with cairo, this will
strongly depend on the (x,y) coordinates of the moveto/lineto commands.
