Bug #21841: bootstraptest is failed with OpenSUSE leap 16.0

• Status: Open
• Assignee: -
• Target version: -
• Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN

[hsbt (Hiroshi SHIBATA)]

I update OpenSUSE leap instance to 16.0 from 15.x. After that, bootstraptest is failing with Ruby 3.2-3.4. Ruby 4.0 and master are working fine.

Ruby 3.4: https://rubyci.s3.amazonaws.com/opensuseleap/ruby-3.4/log/20260115T223828Z.fail.html.gz

stderr output is not empty

Does anyone know of a commit that might have fix this issue?

[nobu (Nobuyoshi Nakada)]

Maybe related to #21715?

[hsbt (Hiroshi SHIBATA)]

@nobu (Nobuyoshi Nakada) Thanks. I backport #21715 to ruby_3_3. I'll wait to see next build.
