Dmitry Kalinkin commented on PARQUET-1438:
------------------------------------------

Perhaps this is an arrow issue then?

> [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

> 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.
