Issue #12500 has been updated by jeremyevans0 (Jeremy Evans). I submitted a pull request to handle this ArgumentError: https://github.com/ruby/ruby/pull/8270 ---------------------------------------- Bug #12500: TestProcess#test_aspawn_too_long_path fails on mips with "argument too big" https://bugs.ruby-lang.org/issues/12500#change-104244 * Author: zeha (Christian Hofstaedtler) * Status: Open * Priority: Normal * ruby -v: ruby 2.3.1p112 (2016-04-26) [mips-linux-gnu] * Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: REQUIRED ---------------------------------------- Recently in Debian we've enabled `make check` and this is one of the test failures we get for ruby2.3, on mips: ``` TestProcess#test_aspawn_too_long_path [/«PKGBUILDDIR»/test/ruby/test_process.rb:1602]: [ruby-core:34833] #7904 [ruby-core:52628] #11613.

Please also backport any fixes for this to 2.3. -- https://bugs.ruby-lang.org/
