Subject: [ruby-core:37859] [Ruby 1.9 - Bug #4992] finalizer中のThread.newでSEGV


Issue #4992 has been updated by Shota Fukumori.


Oops, I sent this issue into ruby-core.

I wrote this issue again in English:

-- Thread.new in finalizer raises SEGV

The following code raises SEGV sometimes:

$ ruby -e'ObjectSpace.define_finalizer(""){Thread.new{}}'  
$ ruby -e'ObjectSpace.define_finalizer(""){Thread.new{}}'
SEGV received in SEGV handler

But this code raises SEGV authenticity:

$ ruby -e'ObjectSpace.define_finalizer(""){2.times{Thread.new{}}}'
SEGV received in SEGV handler
$ ruby -e'ObjectSpace.define_finalizer(""){2.times{Thread.new{}}}'
SEGV received in SEGV handler
