Fix Version/s: cpp-1.5.0
> [C++] Reading of files with dictionary size 0 fails on Windows with bad_alloc
> -----------------------------------------------------------------------------
>
> Key: PARQUET-1333
> URL: https://issues.apache.org/jira/browse/PARQUET-1333
> Project: Parquet
> Issue Type: Bug
> Components: parquet-cpp
> Affects Versions: cpp-1.4.0
> Environment: Microsoft Windows 10 Pro with latest arrow master.
> Reporter: Philipp Hoch
> Priority: Major
> Fix For: cpp-1.5.0
>
>
> Account for total_size being 0, having no dictionary entries to allocate for.
> The call with size 0 ends up in arrows memory_pool,
> [https://github.com/apache/arrow/blob/884474ca5ca1b8da55c0b23eb7cb784c2cd9bdb4/cpp/src/arrow/memory_pool.cc#L50],
> and the according allocation fails. See according documentation,
> [https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/aligned-malloc].
> Only happens on Windows environment, as posix_memalign seems to handle 0
> inputs in unix environments.
