Nothing strange about it at all......
Address $5417e3c0 is pointing at a long 0.
I always use the new syntax for ASM.
The newsyntax would be: MOVE.L ($5417e3c0),A6
it makes it clearer & if you forget the # for an immediate value
it flags an assembler error....
I think what you assumed it was doing is moving the
immediate value of #$5417e3c0 into A6,
which should have resulted in A6 containing $5417e3c0,
but it didn't ehh.....
