Dear debrebuild developers,
the libraries and executables of many cmake-based packages gain extra
zero bytes in their .dynstr ELF section when rebuilt. (This accounts for
about 15% of the failed rebuilds.)
From <https://reproduce.debian.net/api/v0/builds/105657/diffoscope>:

Oddly, sometimes the number of zero bytes added is odd.
