[Devel] Bug#94041: Freetype (either version) not 64-bit clean

[Anthony Fok]

Hello all,

I just received a _critical_ bug report on FreeType
from a fellow Debian developer.  It does look quite serious
because neither FreeType 1 nor FreeType 2 works properly
on a 64-bit platform like Alpha, Sparc64 and the upcoming IA64.

So yes, please do try to fix it to make FreeType truly
a universal font engine.

Thanks,

Anthony

Package: freetype
Version: 2.0.2.20010412-1
Severity: critical

All versions of freetype are not 64-bit clean.  The headers are littered
with things like:
    TT_ULong   ulUnicodeRange1;        /* Bits 0-31   */
    TT_ULong   ulUnicodeRange2;        /* Bits 32-63  */
    TT_ULong   ulUnicodeRange3;        /* Bits 64-95  */
    TT_ULong   ulUnicodeRange4;        /* Bits 96-127 */

On Alpha (also IA64 and possibly sparc64), ULong=64bit unsigned
long.  This causes problems when running some things, such as ttfbanner
from freetype-tools.  Here's a sample from Alpha...the segfault is because
of 64-bit issues:
        address@hidden:
        ~ > ttfbanner -p 8 ./ARIAL.TTF test
        Segmentation fault

This has been brought up with upstream by myself and one other Tru64
porter, but at the time, they denied that it was a problem despite
numerous examples of segfaults and problems.

This has been a known issue for quite some time, but I attempted to make a
patch to fix it.  Unfortunately, the source defied all attempts.  If you
can speak with them and/or make the code NOT assume that longs and
pointers are not 32-bits, the entire Alpha-Linux world would owe you a
beer :-P
