Issue #20726 has been reported by luke-gru (Luke Gruber). ---------------------------------------- Bug #20726: Issue with hash without braces when assigned to constant with ractor literals https://bugs.ruby-lang.org/issues/20726 * Author: luke-gru (Luke Gruber) * Status: Open * ruby -v: 3.4.0dev * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- ```ruby a = 'hi' A = ['hello' => a] p A ``` gives: ``` ./ruby -I../ruby/lib -I. -I.ext/x86_64-linux -I.ext/common -r./x86_64-linux-fake ../ruby/test.rb -- raw disasm-------- trace: 1 0000 putchilledstring "hi" ( 3) 0002 setlocal_WC_0 3 ( 3) trace: 1 0004 newarray 1 ( 4) 0006 putspecialobject 3 ( 4) * 0008 setconstant :A ( 4) trace: 1 0010 putself ( 5) 0011 opt_getconstant_path [:A] ( 5) 0013 opt_send_without_block <calldata:p, 1> ( 5) 0015 leave ( 5) --------------------- ../ruby/test.rb:4: argument stack underflow (-1) ../ruby/test.rb: compile error (SyntaxError) ``` This is due to a line in `compile.c`, function `compile_shareable_literal_constant`: ```c if (!RNODE_HASH(node)->nd_brace) { } ``` I'm not sure why this condition is there so I'm not confident in making a fix. Also, my git-fu isn't the best so I can't track down the right commit where it was added. -- https://bugs.ruby-lang.org/
