Hi Mariano,<div><br></div><div> can you create an image that exhibits the crash from start-up? If so, please email it to me and I'll fix this asap.<br><br><div class="gmail_quote">On Mon, Oct 3, 2011 at 2:35 AM, Mariano Martinez Peck <span dir="ltr"><<a href="mailto:marianopeck@gmail.com">marianopeck@gmail.com</a>></span> wrote:<br>

I am using the trick of #cannotInterpret: and I discover a problem with it. Basically, it is when doing something like this:<br>
<br>MyProxy >> cannotInterpret: aMessage<br>
<br>Error signal: 'ups...'.<br><br>In this case, the debugger comes in but after one or 2 times I press in the debugger line of #cannotInterpret: (to debug it), it crashes. As far as I could see with gdb, the problem is in MethodContext >> #printDetails:<br>
If I comment the contents of such method, I have no crash at all. I think that in this scenario where I throw an arror inside #cannotInterpret can reach a situation where you don't have temps or values or receiver or something and that's why it crash.<br>
Furthermore, previous VM version, do NOT have this problem. <br><br>I will try to dig a little more, but if you give me a hint, I appreciate it. <br><br>Here is the bt and the stack:<br><br>Program received signal EXC_BAD_ACCESS, Could not access memory.<br>
