Hello,

I noticed that gnustep, which relies on libffi (or ffcall
alternatively), malfunctions badly on netbsd/sparc. Since ffcall
doesn't build currently, libffi is my only choice, I installed the
pkgsrc version.
Suspecting a libffi malfunction, I build the pkgsrc version and I cd'd to
/usr/pkgsrc/devel/libffi/work/gcc-3.3.5/libffi


there is a ffitest script, running it fails this way:

...
6.55
6
structure test 9 ok!

Enter FFI_CLOSURES

1 2 3 4 127 429 7 8 9 10 11 12 13 19 21 1 3: 680
Bus error (core dumped)


so possibly my suspects that ffcall is broken on this platform are true.
