Subject: [ruby-core:117684] [Ruby master Bug#20452] Ruby 3.3 on Alpine Linux results in a relatively shallow SystemStackError exception
Date: Wed, 24 Apr 2024 13:41:45 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-20452.20240424134145.53314@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-20452.20240424134145.53314@ruby-lang.org
Issue #20452 has been reported by Earlopain (A S).
----------------------------------------
Bug #20452: Ruby 3.3 on Alpine Linux results in a relatively shallow SystemStackError exception
https://bugs.ruby-lang.org/issues/20452
* Author: Earlopain (A S)
* Status: Open
* ruby -v: 3.3.1
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
This is a redo of https://bugs.ruby-lang.org/issues/14387, reported against a non-eol version. The same issue still applies on recent rubies, though I personally only have tested 3.3 and 3.2:
```rb
n = 100000
res = {}
1.upto(n).to_a.inject(res) do |r, i|
r[i] = {}
end
def f(x)
x.each_value { |v| f(v) }
end
f(res)
```
The patch from https://bugs.ruby-lang.org/issues/14387#note-13 still works, though as per https://bugs.ruby-lang.org/issues/14387#note-16 it can't be accepted as is.
With the patch applied:
```

from /usr/local/bin/irb:25:in `<main>'
```
Without the patch:
```

from (irb):8:in `f'
from (irb):8:in `block in f'
from (irb):8:in `each_value'

from /usr/local/bin/irb:25:in `<main>'
```
To reproduce, I have removed lines 102-105 from https://github.com/docker-library/ruby/blob/f5753434bb23041dd9913bb7b650e7be735e03c0/3.3/alpine3.19/Dockerfile. Check out the previous ticket for more information, there are a few conversations about possible solutions.
