[Pharo-users] Pharo 6, bad debugger behaviour

Good point by Norbert - I should have referenced a bug - but interested in others experience and I will annotate that bug.

For me, this isn’t a recursion thing, it’s a dnu when restarting a method (not sure if many people do this - but it’s a key Smalltalk feature in my mind - so it should work well).

Also my image recovers fine when I shut down the debuggers.

Interested in others experience and I guess I should try and use 7 more to see if it’s there too.

Fearing the worst (after a few seconds), if I repeatedly press cmd . (Say 5 times) after 10 seconds more it comes back with 30 debugger Windows typically with something like Instance of Xxxx dnu: #someMethod (which is legit as I might have a now corrupt inst bar).
