File chasen-initialize-memory.patch of Package chasen
Author: Bernhard M. Wiedemann <bwiedemann suse de>
Date: 2017-11-08
Problem: when building the ipadic package it differed for every build
because its chadic.dat contains uninitialized memory
from the da_dat_t structure's padding bytes
Solution: initilize memory (including padding added by compilers)
before use
