Issue #17192 has been reported by wanabe (_ wanabe).

----------------------------------------
Bug #17192: ISeq.load_from_binary can cause BUG if binary is a rbinc-derived
https://bugs.ruby-lang.org/issues/17192

* Author: wanabe (_ wanabe)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
The following command can cause BUG.
```
$ ruby -e 'print RubyVM::InstructionSequence.of(1.method(:abs)).to_binary'|ruby -e 'RubyVM::InstructionSequence.load_from_binary(ARGF.read)'
-e:1: [BUG] ibf_load_builtin: table is not provided.

I think that `ISeq.of` should raise some kind of exception on the case.
Or `ISeq.load_from_binary` may raise an exception.
