OK I'll wait for another use case or until it happened to me. Like a usecase from a fresh image.
It's just it may be due to the new inspector, new debugger or new compiler. Just wondering.
It's definitely not due to the new code. I see it occasionally in Squeak images without Opal.

Ok I have the error too.
Strangely enough, the error is triggered because the third BlockClosure>>#on:do: context has 2 temporaries instead of 3.
Igor / Esteban do you have a clue ? Why a context would have less temporaries than expected ? Problem from context creation out of the stack ?
No. It'll be popping too much off the stack. See e.g. ContextPart>>jump.
I will try to find some time to look at this problem. Though it is not an easy one it will take some time to be fixed.

Hello,
I'm interested.
Please send me the image in private mail not to overload the mailing list with large attachment. Alternatively, give me a place where I can download it.

The steps to reproduce are: open the image, execute 1halt, close debugger ?
There are three debuggers already open. Just close them. The third close generates the error. A confounding factor may be your running this on a different VM. This is mine...

The error still occurs if I try the image on the latest VM, but then again the effect may already be in effect.
btw, Its not directly causing me pain since I can continue in the image, but still thanks for checking it out for general improvements.

** For a while now, every now and then when closing a debugger I have been getting an "Unwind error during termination"
I happened to have saved the image moments before it just occurred again. From opening that save error can be reliably triggered in three clicks. I can provide this image if anyone is interested in it.
