Details

(Keywords: assertion, testcase)

The following testcase asserts on TI revision d3215d1e985a (run with -m -n -a),
tested on 64 bit:

var HOTLOOP = 100; // works, 10 isnt enough though
function jit(on)
{
  options().match
}
function options() { return "tracejit,methodjit"; }
gczeal(2);
for (i = 0; i < HOTLOOP ; ++i) { jit(jit(42, [])); }
We weren't always emitting the necessary rejoin sites in call paths, so that if we invoked a call IC from within an inlined frame which triggered a recompilation, we couldn't rejoin.  This coalesces things so that the rejoin sites are always generated in the same way and place for calls.
