Subject: [ruby-core:50279] [ruby-trunk - Bug #7459] at_exit { Thread.new {} } broken in r37921


Issue #7459 has been updated by zenspider (Ryan Davis).


This is blocking my merge of minitest to trunk for 2.0 preview.
----------------------------------------
Bug #7459: at_exit { Thread.new {} } broken in r37921
https://bugs.ruby-lang.org/issues/7459#change-34106

Author: zenspider (Ryan Davis)
Status: Open
Priority: Urgent
Assignee: 
Category: core
Target version: 2.0.0
ruby -v: 2.0


ruby -e 'p Thread.current; at_exit { p Thread.current; [Thread.new {}].map(&:join) }'

outputs:

#<Thread:0x007feeb28b0fa8 run>
#<Thread:0x007feeb28b0fa8 dead>
-e:1:in `new': can't alloc thread (ThreadError)
	from -e:1:in `block in <main>'

Either the main thread shouldn't be marked as dead until it actually is, or the check in thread_s_new should be expanded to include whatever thread is responsible for the at_exit run.
