Bug #3672: PTY.getpty with non exist program
http://redmine.ruby-lang.org/issues/show/3672

起票者: Yui NARUSE
ステータス: Open, 優先度: Normal
カテゴリ: core, Target version: 1.9.3
ruby -v: ruby 1.9.3dev (2010-08-09 trunk 28938) [x86_64-freebsd8.1]

存在しないプログラムを指定して PTY.getpty を呼ぶと [BUG] になります。
PTY.getpty 側での対処と rb_fork_err 側での対処がありえますが、
とりあえず後者側でも対処が必要でしょう。

% ./ruby -rpty -e'PTY.getpty"a"'               
-e:1: [BUG] rb_sys_fail(fork failed) - errno == 0
