----------------------------------------
Bug #17534: Pattern-matching is broken with find pattern
https://bugs.ruby-lang.org/issues/17534#change-90242
* Author: zverok (Victor Shepelev)
* Status: Closed
* Priority: Normal
* Backport: 2.5: DONTNEED, 2.6: DONTNEED, 2.7: DONTNEED, 3.0: DONE
----------------------------------------
The minimal reproduction code:
```ruby
case [1, 2, 3]
in y
puts "branch1"
in [*, x, *]
puts "branch2"
else
puts "branch3"
end
```
This outputs long "raw disasm" sequence, and then
```
---------------------
break_pm.rb:6: argument stack underflow (-1)
break_pm.rb: compile error (SyntaxError)
```
```
$ ruby -v
ruby 3.1.0dev (2021-01-13T09:12:49Z master 6f6dfdcc68) [x86_64-linux]
