[Sbcl-devel] linux/ppc ffi bug, "long long" arguments and return values

[Luis O. <lu...@gm...>]

Hello,

Here's a small test case for this bug related to passing or receiving
long-long values to/from foreign functions.

$ uname -a
Linux pomajxego 2.4.22-ben2 #2 Mon Nov 10 18:22:42 WET 2003 ppc
GNU/Linux

$ sbcl

This works fine on darwin/ppc and linux/x86. Also, getting and setting
foreign variables of type long-long seems to work, including on
linux/ppc.

Thanks,
