I've just run across interesting memory corruption in Ada: by
duplicating DECL node for nested function we ended up with pointer to
ggc_freeded DECL_STRUCT_FUNCTION.  I have patch to always make functions
nonlocal that might solve this problem as well (as we get methods for
C++ local classes).  I am just on the way to Prague, but I will break it
up from my tree then.
