garbd binary from linux generic "glibc_214" tarballs segfault with config file

When using binary tarballs from mariabd.org on Ubuntu 16.04 garbd from the "glibc_214" tarball crashes when reading options from a config file.

The garbd binaries from the other two tarballs work fine with the same config file, and all three binaries work fine when passing the same options via command line options directly instead of putting them into a config file.

Looking further the content of the config file doesn't even really matter, garbd even crashes on an empty config file.

Core file backtrace:
