Does this need to be TEST_F or can it just be TEST? It doesn't appear to be using any of the members of TestBuffer.

I removed the fixture and made everything TEST since none of them were using it

Would ASAN be able to detect this kind of lifetime error?

I think so, and you would segfault if you tried accessing the memory that had already been freed

Many other libraries interchange binary data with `std::string`. This makes it easy to wrap such data in an `arrow::Buffer`. It may be worth adding a function that creates a buffer from a string, but owns its memory. I also deprecated `arrow::GetBufferFromString`, which shouldn't have been public in the first place, since the new ctor is more general Author: Wes McKinney <[email protected]> Closes apache#1147 from wesm/ARROW-1600 and squashes the following commits: f60f502 [Wes McKinney] Remove TestBuffer fixture 644bf2b [Wes McKinney] Add Buffer ctor that wraps std::string
