<pre wrap="">Printing this before pressing Command+d on the Process browser:
Link allSubInstances count: [ : e | e nextLink==e]
reports 0.
AFTER I press Command+d, I have to press Command+. to interrupt the
infinite recursion, which exposes the debugger which is trying to open
the debugger on the process I selected (see below for the stack). NOW
Link allSubInstances count: [ : e | e nextLink==e]
reports 1, and the one instance is the Process I was trying to debug.
So, I overrode Process>>#nextLink: setter to guard against setting it
to himself and repeating the test. The guard was never hit, but the
same condition ('nextLink' referring to itself) still formed. This is
impossible since that's the only writer of that variable unless the VM
or other low-level mechanism is setting the Process' nextLink.
================
Here's the stack of trying to invoke 'debug' from the Process Browser.
A MethodContext is just trying to render its printString as part of
Debugger operations but it can't because of the cycle. Any ideas?
