Description

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]:

[Errno::ENOENT, Errno::E2BIG] exception expected, not.

---------------

I think is caused by some array or string mangling code used by Process.spawn, but can't be sure.

Please also backport any fixes for this to 2.3.
