Anyone got a tree or RTL corruption bug?

[Zack Weinberg]

I'm trying to make debug_tree/rtx more robust in the face of corrupt
tree/RTL structure.  I finally have a sensible way to check whether
dereferencing random pointers will cause a segmentation fault.  But
now I can't find any corruption bugs to test them on.  Can anyone
suggest something?
