If this is happening in 1.7 but not 1.6.7 it is a regression and an important one since win32ole depends on registry working (and obviously is also important if you want to use registry itself ).

It appears to still occur, if the key exists and you try and read it, the seg fault occurs (mri is ok).

[master 40b879f] is the last piece fixed. Our new release of jffi fixed a bulk of this.

Nice. If it's absent it doesn't seg fault. That is good.
If it's present, I think it still does though, even with a clean build.

Roger, I did several things (although it was purely reading registry entries) with nothing blowing up. Could I also you to try this in 1.8 mode as well to figure out if this is a general issue with ffi/jnr? Also if you could provide some registry script which would be meaningful on my windows (any windows) box, then it would be nice to get a reproduction I could screw around with. A gist or attachment of your hs_err file would help too.

ok attempted to attach. I was able to reproduce the failure on another (windows 7 64 bit) box (32 bit java). Failure seems to occur in either 1.9 or 1.8 modes.

use like @screen_reg = Win32::Registry::HKEY_CURRENT_USER.create "Software
os_screen_capture"; @screen_reg['last_init_config_was']

Hmm, I am not seeing this error at all, but I am using Win 7 64 bit with 64 bit VM. I wonder if it is a mixed address issue of some kind?

It does seem to work fine with 64 bit VM here, as well.

still present with jruby 1.7.0.preview2.dev (ruby-1.9.3-p203) (2012-07-09 b836c0f) (Java HotSpot(TM) Client VM 1.6.0_33) [Windows 7-x86-java]

if you install VLC for instance (or just create any registry key, then attempt to read it).
Win32::Registry::HKEY_LOCAL_MACHINE.open('Software\Wow6432Node\\VideoLAN
VLC')['installDir']

causes the seg fault.
