[Devel] problem in ftbbox.c

[Mikey Anbary]

Hi

 

In file ftbbox.c function BBox_Conic_Check 

 

my arguments are y1 = 944, y2 = 946,  y3 = 948 

so FT_MulDiv( y2 - y1, y2 - y1, y1 - 2*y2 + y3 ) gets called with

    FT_MulDiv(2,2,0)

and then in FT_MulDiv C == 0 so we fall into

    a = 0x7FFFFFFFL;

Which totally messes the bounding box ,

The glyph is rendered properly so it must be a bug in this rare case,

I have no idea what should be done but I'm sure somthing is wrong.

 

Regards
