Dmitry Kalinkin resolved PARQUET-1438.
--------------------------------------
Resolution: Fixed
Fix Version/s: 1.12.0
This got resolved after fixing the issue in arrow-cpp
> [C++] corrupted files produced on 32-bit architecture (i686)

> I'm using C++ API to convert some data to parquet files. I've noticed a
> regression when upgrading from arrow-cpp 0.10.0 + parquet-cpp 1.5.0 to
> arrow-cpp 0.11.0. The issue is that I can write parquet files without an
> error, but when I try to read those using pyarrow I get a segfault:

> I have not been able to dig to the bottom of the issue, but it seems like the
> problem reproduces only when I run 32 bit binaries. After I learned that, I
> found that 32 bit and 64 bit codes produce very different different parquet
> files for the same data. The sizes of the structures are clearly different if
> I look at their hexdumps. I'm attaching those example files. Reading
> "32.parquet" (produced using i686 binaries) will cause a segfault on macOS
> and linux, "64.parquet" will read just fine.
