The problem is right here:
{"sql-bin-update-same", OPT_SQL_BIN_UPDATE_SAME,
"The update log is deprecated since version 5.0, is replaced by the binary \
log and this option does nothing anymore.",
0, 0, 0, GET_BOOL, NO_ARG, 0, 0, 0, 0, 0, 0},
We are telling handle_options() to store a value at the 0 address. We should have something like GET_DEPRECIATED instead of GET_BOOL, or find some other way to deal with depreciated options. Maybe add a blackhole variable bool opt_bool_depreciated ?
