[ft] core dumps with freetype 2.1.9 and AIX 5.2

[Mark Frost]

Hello.  I'm trying to build freetype 2.1.9 on an AIX 5.2 platform.  I'm
using gcc 3.4.3 using AIX's ld (i.e. non-gnu).

I'm using the following simple program as a test:

 /* Cribbed from GD library's config script test */

/* We use char because int might match the return type of a gcc2
   builtin and then its argument prototype would still apply.  */
char FT_Init_FreeType ();
int main ()
{
FT_Init_FreeType ();
return 0;
}

I compile that using:

/opt/www/bin/gcc -o ct -g -O2 -DFT_DEBUG_LEVEL_TRACE=1
-I/opt/www/include/freetype2 -I/opt/www/include -L/opt/www/lib
-Wl,-blibpath:/opt/www/lib/gcc/powerpc-ibm-aix5.2.0.0/3.4.3:/opt/www/lib/gcc/powerpc-ibm-aix5.2.0.0/3.4.3/../../..:/usr/lib:/lib
-L/opt/www/lib test.c -lfreetype  -lpng -lz -lm  -liconv

and it compiles fine.  When I run it I get the infamous "Segmentation
fault (core dumped)".  I had been seeing core dumps with GD and
displaying fonts and now I'm down to suspecting freetype.

Here's the little stack trace from this core dump:

Here's info on my gcc if it's relevant:

$ gcc -v

gcc version 3.4.3


Unfortunately, the project I'm working on requires that this be
functional and I've spent lots of time pouring over the code and
watching it run and I've not come to any conclusions as to what's going
on.  But then again, I'm no expert either :-)

Thanks
