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 ?

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.

Hi Clément, I really appreciate you having a look but perhaps it would be worthwhile to gather some more use cases before spending too much time on it - unless the challenge is particularly appealing :) . Partly I was checking the wider awareness of this particular error. Even though I've seen it a few times, if no-one else has, then perhaps I should ensure I'm on the latest VM and see if it occurs again. Then might be a better time to attack it.

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.
