[HarfBuzz] hb-view assert with graphite version of Scheherazade

[Khaled Hosny]

Hi Behdad,

I get an assertion failure from hb-view when using Graphite version of
Scheherazade (http://scripts.sil.org/graphitefonts):

ERROR:helper-cairo.cc:356:void helper_cairo_line_from_buffer(helper_cairo_line_t*, hb_buffer_t*, const char*, unsigned int, double): assertion failed: (hb_glyph[i].cluster > hb_glyph[i+1].cluster)

I didn't have this few days ago.

Regards,
 Khaled
