Description

In C++ arrow it can currently occur that uninitialized data created by the builders is written to IPC memory. The goal of this issue is to identify these cases and set the memory to zero.

Note that most of these cases have already been identified by valgrind and fixed in the past.

Some of the considerations and benefits are discussed in this github PR:
