Xen devel - Jun 2012 - how to find out lea instruction causes skype crash when starting

Hi david,
    I find you signed off a patch about "x86: emulate lea with two register
operands correctly" .In this patch,you described skype does a lea
instruction and will crash when starting if it does not get the exception.I
have used a tool named mentorKG.exe to make a LICENSE.TXT.but the software
crashes when starting.I used your patch,and find it works well.I wonder how
can you find it''s the lea instruction which cause the application
software
crash when starting.Can you give me some methods?

Skype told us what their application was doing.
