[Pharo-users] Stability of Pharo 7 vs 6?

Hmmm Ben - its interesting that other languages/environments show that same stack error - and they seem to hint at memory issues- although in our case I’m working with a simple Pharo image that has very little in it (I’ve had much larger ones in Pharo 6.x without issue).

Interestingly - since launching a zeroconf image and not going full screen - its been running now for 1.5 days without a crash (whereas previously around 24 hours or less it would crash).

Having said this - I’ve just started another clean zeroconf image (not full screen) and during the initial metecallo (iceberg) load - its seg faulted again - but this one I think is iceberg related as the crash.dmp looks a bit different, and I did notice that it was loading my baseline a bit slowly (and stifling with some of the dependencies, making me think that something timing related might be at issue).

Having said this - I’m still not having the smooth ride others are reporting - and 7 is still suspect to me.

I’m kind of suprised this isn’t getting much traction from the core team - and I wonder if I should post this on the dev list instead?
