Description

The code in TABLE_SHARE::init_from_binary_frm_image() is not safe for broken FRM files.

In debug mode it can crash on assert.
In release mode its behavior is not predictable.

interval_nr=  (uint) strpos[12];

...

DBUG_ASSERT(interval_nr); // Expect non-null expression

...

vcol_info_length= interval_nr;

vcol_expr_length= vcol_info_length -

                          (uint)(FRM_VCOL_OLD_HEADER_SIZE(opt_interval_id));

...

The same problem presents in the branch for MYSQL57_GENERATED_FIELD (since 10.2), it's reported as a separate issue ~~MDEV-16518~~.
