Re: Bus Error while trying to run the ffi_closure example in the documentation...
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!
