Subject: [ruby-core:75355] [Ruby trunk Bug#12346][Feedback] Ruby 2.3.0 64-bit (mingw64-32) WIN32OLE_TYPE.typelibs seg faults on Windows 10 64-bit

Issue #12346 has been updated by Nobuyoshi Nakada.

Status changed from Open to Feedback

I can't reproduce it with the trunk and 2.3.1 on Windows 7.
Probably it is related to the content of your registry.
Could you try building with `-O0` and running from a debugger?

Bug #12346: Ruby 2.3.0 64-bit (mingw64-32) WIN32OLE_TYPE.typelibs seg faults on Windows 10 64-bit

* Author: Allen Hewes
* Status: Feedback
* Priority: Normal
* Assignee: cruby-windows
* ruby -v: ruby 2.3.0p0 (2015-12-25 revision 53290) [x64-mingw32]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
Ruby Windows binaries are from RubyInstaller.org.

Seg fault also happens with Ruby 2.3.1 using the same 64-bit DevKit.

in the test suite file test/win32ole/test_win32ole_type.rb, there is the test
test_s_typelibs:

def test_s_typelibs 
  tlibs = WIN32OLE_TYPE.typelibs.sort 
  tlibs2 = WIN32OLE_TYPELIB.typelibs.collect{|t|t.name}.sort
  assert_equal(tlibs2, tlibs) 
end 

Ruby 2.3.0 64-bit produces segmentation fault at both places:
  tlibs = WIN32OLE_TYPE.typelibs.sort
  tlibs2 = WIN32OLE_TYPELIB.typelibs.collect{|t|t.name}.sort 

very basic one line check for each test:
ruby.exe -e "require 'win32ole'" -e "puts WIN32OLE_TYPE.typelibs.count"
ruby.exe -e "require 'win32ole'" -e "puts WIN32OLE_TYPELIB.typelibs.collect{|t|t.name}.count"

fails in:
ruby-2.3.0-x64-mingw32 (see attachments)

works in:
ruby-2.3.0-i386-mingw32 (572)
ruby-2.2.4-i386-mingw32 (572)
ruby-2.2.4-x64-mingw32 (574)
ruby-2.1.8-i386-mingw32 (572)
ruby-2.1.8-x64-mingw32 (574)

I've attached the crash outputs for both:
WIN32OLE_TYPE.typelibs.sort = ruby-2.3.0p0-test_s_typelibs-seg-fault.txt
WIN32OLE_TYPELIB.typelibs.collect{|t|t.name}.sort = ruby-2.3.0p0-test_s_typelibs-collect-seg-fault.txt
