I suggest uploading new upstream releases to experimental to know the
behavior in each architecture. For MISSING lines, an easy fix is to
exclude the fault architectures. E.g. to exclude i386 and x32:

(arch=!i386 !x32)(c++)"gensios::gensio_cpp_vlog_handler(gensios::gensio_os_funcs*,
gensios::gensio_log_levels, char const*, __va_list_tag*)@Base"
