The catch handler table is combined with iseq block. This is to prevent the structure from growing by adding a field for the catch handler table to the `mrb_irep` structure. "iseq block" and "catch handler table": [number of catch handler table (2 bytes)] [number of byte code (4 bytes)] [iseq (any bytes)] [catch handlers (multiple of 7 bytes)] catch handler: [catch type (1 byte)] [begin offset (2 bytes)] [end offset (2 bytes)] [target offset (2 bytes)] catch type: enum mrb_catch_type (0 = rescue, 1 = ensure) begin offset: Includes the specified instruction address end offset: Does not include the specified instruction address target offset: replaces pc with the specified instruction address This table is not expanded by `read_irep_record_1()`. The necessary elements are expanded one by one when used.
