Backport changed from 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN to 2.7: DONTNEED, 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED Thank you for reporting this bug. I have a fix here: https://github.com/ruby/ruby/pull/7044 ---------------------------------------- Bug #19284: Integer overflow when using RUBY_GC_HEAP_INIT_SLOTS environment variable https://bugs.ruby-lang.org/issues/19284#change-100887 * Author: zeke (Zeke Gabrielse) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-darwin19] * Backport: 2.7: DONTNEED, 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED ---------------------------------------- If you set the environment variable `RUBY_GC_HEAP_INIT_SLOTS` to anything other than `0`, an integer overflow runtime error occurs: ```ruby RUBY_GC_HEAP_INIT_SLOTS=10000 ruby -e 'puts "hello, world!"' # => ruby: integer overflow: 3689348814741910508 * 8 > 18446744073709551615 (RuntimeError) ``` At this time, I'm not sure if this is platform-specific, but it's failing on Darwin as well as Heroku's environment (Linux). -- https://bugs.ruby-lang.org/
