ruby 4.1.0dev (2026-06-15T10:28:20Z master c2879d4eb1) +YJIT +PRISM [x86_64-linux]

Backport:

3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN

[ruby-core:125771]

Description

With the latest Ruby master, enabling YJIT causes a SEGV with the following code:

class C
  def foo
    Hash.new {|h, k| h[k] = [] }
  end
end

class D < C
  define_method(:foo) do
    super()
  end
end

1000.times { D.new.foo }

$ ruby --yjit test.rb
<internal:hash>:38: [BUG] Segmentation fault at 0x0000000000000001
ruby 4.1.0dev (2026-06-15T10:28:20Z master c2879d4eb1) +YJIT +PRISM [x86_64-linux]

According to git bisect:

d256629bf9e194838d1837be74dcc0b8ff0bcfd6 with YJIT doesn't crash,
ea7d3eb89b8c5192c0cf9a885a17b0aeaef1067a without YJIT doesn't, and
ea7d3eb89b8c5192c0cf9a885a17b0aeaef1067a with YJIT does

So I suspect ea7d3eb89b8c5192c0cf9a885a17b0aeaef1067a is the culprit.

@alanwu (Alan Wu) Could you take a look?

Here is the full trace:
