-------------------------------------
Summary: [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: 1.9.0
Environment: Microsoft Windows 10 Pro with latest arrow master.
Reporter: Philipp Hoch
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.
