Pointed out by Coverity. Introduced in commit 5b8e1da from September 2011 ("Initial pass at zlib bindings".) The asynchronous version of Write() used a pointer to a stack-allocated buffer on flush. A mitigating factor is that zlib does not dereference the pointer for zero-sized writes but it's still technically UB.

Pointed out by Coverity. Introduced in commits 3546383 ("process_wrap: avoid leaking memory when throwing due to invalid arguments") and fa4eb47 ("bindings: add spawn_sync bindings"). The return statements inside the if blocks were dead code because their guard conditions always evaluated to false. Remove them.

@addaleax will your backport trump this PR? Should I be waiting for yours before landing this? |

It should be a pretty much independent thing, I think. So unless you or Ben think it would be easier to backport these together, I see no reason to hold this PR up. |

I can cherry-pick the missing commit after the MaybeStackBuffer change lands, that doesn't have to hold up this PR. |

This is missing commit c50e192. The memory leak exists in v4.x but it depends on the MaybeStackBuffer class that doesn't exist (yet? - cc @addaleax) in v4.x.
