On current svn build (on Ubuntu Feisty), but only on this machine (the one at home runs ok...), if I open a main package and then I change to another main package, the ide crashes with segmentation fault. I rebuilt id with debug; here the backtrace :

Hope it will be useful.... I don't know enough (yet) about upp to find the bug by myself !
Ciao

Looking more in depth, the bug happens when you exit theide after the main package selection, too... so it should be easier to find, I hope.
Just a question : the ::MemoryChech() function does a complete heap check, even the freed blocks ?
Ciao
Max
EDIT : Investigating a bit more, I found that the heap corruption happens (at first) in the function Ide::FlushFile() when the line Editor.Disable() is called. If I suppress this line, the Ide goes a bit further before crashing again.
I guess it's something inside the assist editor....
