[freetype2] master 966ff5a55 1/2: * src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash.

[Werner Lemberg]

branch: master
commit 966ff5a55cbe46e9ae4658e6e0e7ecb1e6e82b07
Author: Werner Lemberg <wl@gnu.org>
Commit: Werner Lemberg <wl@gnu.org>

    * src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash.
    
    The situation can happen if `FT_New_Face` (or one of its siblings) is called
    with a negative index to get the number of contained faces, followed
    immediately by a call to `FT_Get_Postscript_Name`.  While this is not a 
valid
    use of the FreeType library there is no need for a crash.
    
    Fixes #1219.
