Asmadian thinks it's funny when there's a page fault while initializing multitasking (probably in move_stack()):

Man, weird stuff. First the weird VFS bug where gcc decided not to tell me about a syntax error, now this.

Calling some of the functions to print stuff to the screen with a corrupted stack lead to this:

It's actually kind of pretty in a way but finding the problem took a while :p.

Make them fall down to the bottom of the screen :D :D.

EDIT: did anyone see the heart from the first time they looked?

Yes but it has to produce always something with a meaning XD... This is a cool idea for a contest XD

How about running code in 4-plane 16-colour mode, and have the code run without crashing regardless of which plane is enabled. Or something :)

Not the first 1 to do tht, I might add. If you can keep the code, add a cool backwards text command, which does as you see there. turn a bug into a feature. could be fun!

Sure I can XD! Thank you for the suggestion ;) I added this crazy feature to Smile (my OS ;)) and I'm going to add the code to rotate the screen (portrait/landscape view).
