Can you add a test? |

The problem shows up in incremental bind scenarios, e.g. if module "b" has an export * of the members of a module "a", then when "a" is modified, "b" will still show the old exported members of "a". Not sure how to construct such a test, but I have manually verified that the fix solves the problem. |

Ah, got it. In that case, you could use a fourslash test to verify this. |

Computing the merged set of exports for an external module with
export *statements inadvertently overwrites the original set of exports. This PR fixes the issue.
