I've the bug cornered in a VERY simple test case .
http://t3.dotgnu.info/code/dyncall-test.tgz

It prints 
[gopal@sirius dyncall]$ ./test.exe 
dpy : (nil)
window : 42
(x,y) : (1, 2)
(w,h) : (3, 4)
border : (5)
depth : (6)
class : (7)
visual : ((nil))
mask : (cafebabe)

in x86 (pentium4)

And 

-=[gopal@amon-ra:x86_64]=->ilrun test.exe 
dpy : (nil)
window : 42
(x,y) : (1, 2)
(w,h) : (3, 4)
border : (5)
depth : (7)
class : (0)
visual : (0xcafebabe)
mask : (66b000)

on x86_64 .  Strange , but looks like the mask being
passed as visual is the bug here ?. I'm unable to
determine whether this is libffi, pnet's marshalling
or something else . Can the experts have peek at this 
?.
