Accesses to volatile longs don't work in the 64-bit interpreter, and, by
extension, the 64-bit vm.

Run the attached program using

java -sd64 -server -Xint AtomicLong

and get the following output

Saw 400000008
 temp1 4
 temp2 8
Saw 200000007
 temp1 2
 temp2 7
Saw 700000001
 temp1 7
 temp2 1
Saw 100000009
 temp1 1
 temp2 9
Saw 100000007
 temp1 1
 temp2 7
Saw 700000004
 temp1 7
 temp2 4
Saw 100000007
 temp1 1
 temp2 7
Saw 400000007
 temp1 4
 temp2 7

There shouldn't be any output at all.
