I have found a solution: use "--smc-check=all".
This is needed because the JIT::linkCall function (and some other JIT staff) modifying the jitted code, so valgrind must check self modification.
Alternatively we could use valgrind's client request mechanism. That would be cheaper, but I am dubious about how the apple folks would feel about to introduce valgrind into the codebase (we should have at least a build option, and a define for valgrind).
