Re: [ft-devel] Freetype-devel Digest, Vol 146, Issue 8

The prep table seems to be trash. Can another OS uses it?

 The illegal instruction is 0xAF. My private dev branch of FontVal shows a bit 
more info - the private dev shows stack under flow and point out of range 
before the illegal instruction. Unfortunately the release/pub dev branch of 
FontVal organizes things per glyph, so it only shows the final per-glyph fatal 
error, which is the illegal instruction.

 Subject: [ft-devel] all the glyphs in this font are
 unloadable

 Hello, team.
 
 I find a 'problematic' font in which all the glyphs are
 unloadable, they all cause Invalid_Opcode error(error code:
 0x80). The loading flag is FT_LOAD_DEFAULT.
 
 Please check it. Thank you.
