Comment(by mabshoff):
The problem is that siInit doesn't get called on 64 bit OSX (William and I
verified by adding a printf() statement). After this patch it gets called,
but the allocation still fails, so we need to dig a little deeper.
As is the patch is not applicable since we open the mangled name, but
siInit should be declared {{{extern "C"}}} to avoid this.
Cheers,
Michael
