Bug #20477

Updated by ukolovda (Dmitry Ukolov) about 2 months ago

When I create Hash with 8 or more items, I got the error: items: 

 ```bash 
 ruby --rjit -e "a = 1; 1.upto(10) { b={a1: a&1, a2: a&1, a3: a&1, a4: a&1, a5: a&1,    a6: a&1, a7: a&1, a8: a&1} }"

         from -e:1:in `upto' 
         from -e:1:in `<main>' 

 ``` 

 Test ruby file: 
 ```ruby 
 # test.rb  
 # Running: ruby --rjit test.rb 
 a = 1 
 1.upto(10) do 
     b = { a1: a&1,  
           a2: a&1,  
           a3: a&1,  
           a4: a&1,  
           a5: a&1,   
           a6: a&1,  
           a7: a&1,  
           a8: a&1, 
     } 
 end 
 ``` 

 (I described it first in #20475, but it is closed now. Current description is more clear and easy reproduce).
