Note, repro only with --nocrankshaft and --always-opt, no idea if that makes sense.

# Minimized program:
var d = {};
foo = function() {
  print(foo.caller);
}
d.valueOf = foo;
Number(d);
try {
} catch(e) {; }

# Compared nocrankshaft with noturbo_opt

# Flags of nocrankshaft:
--abort_on_stack_overflow --expose-gc --allow-natives-syntax --invoke-weak-callbacks --omit-quit --always-opt --random-seed 948182451 --nocrankshaft
# Flags of noturbo_opt:
--abort_on_stack_overflow --expose-gc --allow-natives-syntax --invoke-weak-callbacks --omit-quit --always-opt --random-seed 948182451 --always-opt --turbo-filter=~

Difference:
- null
+ function Number() { [native code] }

### Start of configuration nocrankshaft:
null

### End of configuration nocrankshaft

### Start of configuration noturbo_opt:
