Re: [ft] Segfault in FT_Get_Name_Index, Solaris 9, FreeType 2.1.8+

[David Turner]

Hello,

I've just tested it with FreeType CVS on a x86 Linux machine, and it 
seems to work
well with the font you sent me. Running with valgrind doesn't show any 
bad memory
access or other errors.

I don't have a Solaris 9 machine here, and won't be able to due much here.
Given the line were the segfault is detected, I suppose that the value 
of the
'service' variable is bogus (and not NULL).

In GDB, could you dump the content of face->internal->services and send it
to me, this would be a good start.

Regards,

- David

PS: By the way, does the problem happens or even changes when compiling
     with/without optimizations ?
