Hi,
i've fixed the problems i had with freetype. The problem was that
Poppler/Fontconfig where calling the wrong version of freetype.
I'm using Qt/E which makes use of freetype by statically linking to
a certain version of freetype (i wasn't aware of this). Poppler and
fontconfig use the

Hello,
the cmap-clazz value is definitely wrong, and there is no way the
charmap was built
with it. In other words, the field has been rewritten after creation of

Can you re-run the program but set a watch on

Hi,
Can you put a watchpoint on the cmap's clazz field to detect where it
is over-written ?
Really, it should give us meaningful information.
I'm not sure if i understand correctly what you wan't me to do.
The crash happens directly after cmap becomes

Sorry, I should have been more accurate.
You should set the watchpoint just after the creation of the FT_CMap
object (this happens in FT_CMap_New in src/base/ftobjs.c). there is
code like this:
if ( !FT_ALLOC( cmap, clazz-size ) )
{
cmap-charmap = *charmap;
cmap-clazz = clazz;

Hi,
thanks for your explanation.
It seems that FT_CMap_New() isn't called at all.

Ahh,
your version of FontConfig is accessing internal fields of FreeType,
and you probably have a version of FreeType installed on your system
that is more recent than the one fontconfig was compiled with.
this also explains the parameter insanity.
try installing fontconfig-2.3.93 or higher,
A segfault happens in this function:
