Remi,
Nice stack trace ;). I'm currently looking into it. Two quick comments:
a) You should run in hosted mode for better startup performance. Build the vm via "./mx.sh --vm server build" and run then via "./mx.sh --vm server vm". Then the only Graal compilations done are the Truffle compilations.
b) The FunCallNode.eval method looks like it is in need of an @ExplodeLoop annotation.
