I would say no -- different allocators might end up being used, and  
that's bad times (especially on win32).  One easy fix is to just  
expose cairo_malloc() and cairo_free(), or, for this specific case,  
just expose a specific allocator for the glyph array  
(cairo_allocate_glyph_array(n)) and a specific deallocator for the  
other side.
