Subject: [ruby-core:71745] [Ruby trunk - Bug #11750] SEGV with Enumerator, yield and proc.
Date: Mon, 30 Nov 2015 05:36:32 +0000 [thread overview]
Message-ID: <redmine.journal-55148.20151130053631.cc7684f081ecca1b@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-11750.20151129162428@ruby-lang.org
Issue #11750 has been updated by Nobuyoshi Nakada.
File bug-11750.log added
Description updated
By bisecting, it raises `SytemStackError` or segfaults since r51243.
~~~
* vm_core.h: remove blockprocval field from rb_proc_t and rb_binding_t.
Instead of this field, mark given block in Proc at rb_env_t::env.
~~~
`Enumerator`, `Generator`, or `Yielder` may need more marking or write-barrier.

Bug #11750: SEGV with Enumerator, yield and proc.
https://bugs.ruby-lang.org/issues/11750#change-55148
* Author: Akira Tanaka
* Status: Open
* Priority: Normal

----------------------------------------
I found SEGV as follows.
```
% cat z.rb
def f
Enumerator.new {|y|
1000000.times {
yield
y.yield
}
}
end
def g
x = proc {}
f(&x)
end
e = g
e.each {}
% ./miniruby z.rb
(snip)
```
