asan.test_dlfcn_jspi is currently failing

[sbc100]

I guess this might have always been failing?

This test is not run in github CI because we only run a small subset of asan tests there.

This test is not run on emscripten-release CI because we don't have a recent version of node there so we set EMTEST_SKIP_JSPI there.

Relevant code is

EM_ASYNC_JS(int, test, (), {
  console.log("sleeping");
  await new Promise(res => setTimeout(res, 0));
  console.log("slept");
  return 77;
});

int test_wrapper() {
  return test();
}

I'm not sure why that would be a problem?

I'm especially not sure why asan would have anything to do with a symbol being undefined or not.. very strange.

lsan works fine.. strange.
