no, I was thinking more or less the same… but still did not looked at it deeply :)
btw… I do not know which randomly picked changes you are talking about. I certainly stopped doing integrations when Eliot started to commit spur stuff, to wait until is more or less ready (bah, with Clement we tried once and it was not worthy, so we rolled back).
then… other stuff: I also don’t know about random methods reformatted. I know I reformatted some, but those I worked on (usually not in VMMaker, with minor exceptions). Of course, I’m not the only one working on those sources, but I certainly did many changes with the years.
Finally: ok, vm shouldn’t crash… but this bug was not vm related but a bad integration (in the new class builder) we rollbacked. That’s why it was not copied to vm-dev :)
