---------------------

../ruby/test.rb:4: argument stack underflow (-1)

```

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.

[ruby-core:119204] [Ruby master Bug#20726] Issue with hash without braces when assigned to constant with ractor literals

[osyo (manga osyo) via ruby-core]

Issue #20726 has been updated by osyo (manga osyo).


This problem was not reproduced with `--parser=prism`, but with `--parser=parse.y`.

```ruby
# shareable_constant_value: literal
# test.rb
puts RUBY_DESCRIPTION

A = [a: 1]
p A
```

This is due to a line in `compile.c`, function `compile_shareable_literal_constant`:

```

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.

Expected:

It works just the same as when pragma `shareable_constant_value: literal` is not given. Which is to say, `[{'hello' => 'hi'}]` is is the value of `A`.

[ruby-core:122099] [Ruby Bug#20726] Issue with hash without braces when assigned to constant with ractor literals

[byroot (Jean Boussier) via ruby-core]

Issue #20726 has been updated by byroot (Jean Boussier).

Status changed from Assigned to Closed

This no longer reproduce with either parser, so I'm going to assume it was fixed.
