* Author: alanwu (Alan Wu)
* Status: Open
* Priority: Normal

* Target version: 
* ruby -v: ruby 2.7.0dev (2019-08-06T18:13:17Z master 8877dbe400) [x86_64-darwin18]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
Crasher: `miniruby -e 'RubyVM::InstructionSequence.compile("case foo in []; end").to_binary'`
It crashes since there is no handling for dumping `TypeError` and `NoMatchingPatternError` in the binary dumper.
