segfault when executing 'SELECT * FROM table' through connector/c++ on a specific table

Original LibreOffice bug report: https://bugs.freedesktop.org/70496

When LibreOffice executes 'SELECT * FROM agendas' (via MySQL Connector/C++ 1.1.2) through a prepared statement (with no parameters), it leads to a segfault in libmariadb. When MySQL Connector/C++ is linked against libmysqlclient18 5.5.31+dfsg-0+wheezy1, the segfault does not happen.

The full original reproduction database can be downloaded from zip file in directory mysqldumps from

but I'm also attaching a smaller example.
