closure api problems

[Aaron Patterson <aaron at tenderlovemaking dot com>]

Hi everyone,

I'm doing my best to get a simple example using the closure API working.
I think I'm missing something simple, but I'm not sure what it is!

I've installed libffi from master (on github) to my home directory and
compiled and linked the cls_uchar.c example against that, and I always
end up with a Bus Error.

Here is the output from my shell:

    $ pwd
    /Users/apatterson/git/libffi
    $ git status
    # On branch master
    nothing to commit (working directory clean)
    $ gcc -o foo \
    -I/Users/apatterson/lib/libffi-3.0.9rc1/include/ -I. \
    -L/Users/apatterson/lib testsuite/libffi.call/cls_uchar.c -lffi
    $ ./foo
    Bus error
    $

Here is the (unfortunately not too helpful) gdb stack trace:

    (gdb) run
    Starting program: /Users/apatterson/git/libffi/foo 
    Reading symbols for shared libraries ++. done
    
    Program received signal EXC_BAD_ACCESS, Could not access memory.
    Reason: KERN_PROTECTION_FAILURE at address: 0x0000000100100080
    0x0000000100100080 in ?? ()
    (gdb) bt
    #0  0x0000000100100080 in ?? ()
    #1  0x0000000100000da4 in start ()
    (gdb)

I'm running 64bit OS X (Snow Leopard).  Any help would be greatly
appreciated!
