Automatic socket flush in stub.cpp is untested #3

Open mpickering opened 5 years ago

mpickering commented 5 years ago

I haven't investigated this at all yet but if you trigger an automatic flush then it segfaults.

You can easily trigger it by requesting the raw closures of all the GC roots.

mpickering commented 5 years ago

The segfault was actually because of forgetting to untag a closure. The automatic flushing logic is still untested.

p9 triggers a flush and no surprise that it breaks.
