Hey all,
So I'm trying to run the ffi_closure example from the libffi
documentation (the one that wraps fputs() ). When trying to run the
program, I get a "Bus Error: 10" and the program crashes.
This is on OS X 64-bit (Lion). Put through gdb, this is what I get:
∞ ~/node-ffi/deps (gyp) $ gdb --args ./out/Debug/test

Awww nobody? Well for easier reference, here's the source code used in
question: https://gist.github.com/1575877 . It's straight from the
libffi docs. Hopefully with the source here somebody else can try
compiling and letting me know the result. Thanks!

Ok so as a little update, the test program I linked to above work on
my Windows XP VM and Ubuntu VMs, so it looks like this might be
something with either the Darwin 64-bit support, or something with my
configuration. If somebody else has an OS X setup and could compile
the example above it would be really helpful. Thanks in advance!

I'm using ffi_closure on OSX (not lion, though) amd64 target and it performs as expected for me.
Have you run the testsuite? there are ffi_closure tests in that.

This might be what you're after:
https://bugzilla.mozilla.org/show_bug.cgi?id=682180
I emailed the patch to one of the libffi lists a while back - not sure
if it ever got merged in.
Cheers,

It would be nice to make sure it's solved for everyone else too ;-).
Anthony, is this patch on the radar for libffi?

There was a similar patch already in the git tree that will go out
with 3.0.11. I'm going through the patch queue today to see if I can
a release candidate out for review soon.
