Description
Here's a snippet that leads to a crash on ruby 2.5.3. I tried to make it as small as possible.
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.
