[ruby-dev:49110] [Ruby trunk - Bug #11277] "code converter not found" Failure since r50887

Issue #11277 has been updated by Naohisa Goto.

Subject changed from "code converter not found" Failure since r50887 on Solaris 10 to "code converter not found" Failure since r50887
ruby -v changed from ruby 2.3.0dev (2015-06-10) [sparc64-solaris2.10] to ruby 2.3.0dev (2015-06-16) [sparc64-solaris2.10]

x86_64 Linux でも50%程度の発生率で再現できました。
r50920 にて確認しました。

~~~
$ echo a0 > /tmp/a0
$ echo a1 > /tmp/a1
$ ruby --disable=gems -EEUC-JP:UTF-8 -e 'Thread.new { File.read("/tmp/a0") }; Thread.new { File.read("/tmp/a1") }.join'
-e:1:in `read': code converter not found (EUC-JP to UTF-8) (Encoding::ConverterNotFoundError)
	from -e:1:in `block in <main>'

2スレッドが同時に同一のenc/transを要求するとダメなようです。
