Bug #15536: Crash on merging specific hashes using keyword splat
https://bugs.ruby-lang.org/issues/15536#change-76343
* Author: decuplet (Nikita Shilnikov)
* Status: Closed
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-linux]
* Backport: 2.4: UNKNOWN, 2.5: REQUIRED, 2.6: REQUIRED
----------------------------------------
Here's a snippet that leads to a crash on ruby 2.5.3. I tried to make it as small as possible.
```ruby
1000.times do
{
**{
a1: nil,
a2: nil,
a3: nil,
a4: nil,
a5: nil,
a6: nil,
a7: nil,
a8: nil,
a9: nil
},
b1: nil,
b2: nil,
a4: nil,
**{ c1: nil, c2: nil },
a7: nil,
a8: nil,
a9: nil,
}
end
```
Results in `*** Error in irb': malloc(): memory corruption: 0x000055ca6c832bd0 ***` (more detail in the attached file).
We came across this on ruby 2.5.3 and as far as I can tell it's no longer a problem on 2.6 but we yet to upgrade.
