[ruby-core:69970] [Ruby trunk - Bug #11352] Sample code Garbage collection dies with an address is T_NONE

[fgifford]

Issue #11352 has been updated by Frank Gifford.

File crash.rb added
File crash_out added
Subject changed from Sample code Garbage collection dies with a to Sample code Garbage collection dies with an address is T_NONE
ruby -v set to 2.2.2p95

> ./crash.rb
./crash.rb:5: [BUG] rb_gc_mark(): 0x85e344c is T_NONE
ruby 2.2.2p95 (2015-04-13 revision 50295) [i686-linux]


I was able to create a crash.rb file (attached) that would generate a crash.  Essentially, we create a large hash of 131 entries in a method and then discard it.  Having 130 entries did not seem to make the crash happen.  The crash happens right away. 

This was first noticed for sure in 2.1.3, it probably exists in 2.1.6 and I verified it here with 2.2.2p95

I believe this may be related to other bugs such as 10803, 10827, and 10163.

Issue #11352 has been updated by _ wanabe.


```
ruby -e 'puts "GC.stress = true; {", *(1..128).map {|i| "#{i} => 0," }, "129 => [],", "130 => [],", "131 => [],", "}"' | ruby
```

It causes similer [BUG] on `ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]` and `ruby 2.3.0dev (2015-07-15 trunk 51015) [x86_64-darwin14]`.
I guess hash.length should be >= 131, and 129th (and also 130th and 131st ?) item of hash should be a target of GC.
