I remeber off-head a similar issue, my first guess would be that 10.5 in 64bit is unexpected.

[rmottola (Riccardo)]

I crafted a patch shich should be used only on 10.5, essentially using 32bit structures even on 64bit. Makes no sense on 10.4, since it is 32bit only. If no issues are reported, neither on 10.6 or later, but in case, possibly just extend.

I didn't make a complicated ifdef stuff, so it is not generelly applicable or upstreamable.

10.5 patch

may be add this patch? I just used it again, confirm it still applies.
