Bug #19263

Updated by k0kubun (Takashi Kokubun) about 2 years ago

``` 
 $ cat test.rb 
 def test(a) 
   case a 
   when true, false 
     a 
   end 
 end 

 test(true) 
 test(true) 

 $ ruby --mjit-verbose=1 --mjit-wait --mjit-call-threshold=2 test.rb 
 /tmp/_ruby_mjit_p237606u1.c: In function ‘_mjit0’:

 I'd like to fix this in master and ask the branch maintainer to backport this fix https://github.com/ruby/ruby/commit/fc03ba50f1ff6c30f7c654f564b4dffbed0844ef to (only) ruby_3_2 branch. 3.2.1.
