--- Comment #1 from Alexey Proskuryakov <ap at webkit.org> ---
There is only one RELEASE_ASSERT in this function, that being:

    RELEASE_ASSERT(isMainThreadOrCheckDisabled());

The process uses both Legacy and Modern WebKit APIs, and we erroneously execute the IPC::Connection destructor on the WebThread instead of the UI thread.

For Apple employees, this looks identical to rdar://problem/51577716&52224515.
