Problems when running Iron (Chrome browser variant)

Created an attachment (id=3332)
Qemu crash

Iron installs fine on rev. 38106, KQEMU. When trying to run, it fires:

(ntoskrnl\ke\i386\exp.c:1044) Kill iron.exe, ExceptionCode: c000001d, ExceptionAddress: 4255b2

So i set KDBG to capture all first exceptions and retried. Effect:

Entered debugger on first-chance exception (Exception Code: 0xc000001d) (Invalid Opcode)
kdb:> bt
Eip:
<iron.exe:255b2>
Frames:
<f07c0055>
Couldn't access memory at 0x71005FFE!

I tried then to attach directly to process. In effect, QEMU triple-faulted. Log attached.
