Subject: [ruby-core:58864] [ruby-trunk - Bug #9205] Assertion failed:	heap_pages_deferred_final == 0


Issue #9205 has been updated by nobu (Nobuyoshi Nakada).


I've misread the code, like as `raise_proc' raises an exception and that triggers the failure.
But the proc raises nothing, then what would trigger it?

Bug #9205: Assertion failed: heap_pages_deferred_final == 0

ruby -v: ruby 2.1.0dev (2013-12-02 trunk 43958) [x64-mswin64_120]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


If I run the following code:

    raise_proc = proc do |id|
      p "Finalizer one on #{id}" 
    end
    10000.times do
      ObjectSpace.define_finalizer(Object.new, raise_proc)
    end

I can see an assertion failure.

"Finalizer one on 24535120"
Assertion failed: heap_pages_deferred_final == 0, file gc.c, line 2111

Same error with ruby 2.0.0p353 (2013-11-22) [i386-mingw32]
