This passes a pointer to a not yet initialized object. Maybe heap allocate it
for safety?

[Lasse Reichstein, 2011/03/29 13:29:55]

Yeah, it's a bit iffy. It should work (the address is safe and it isn't
dereferenced in the constructor), but it's probably safer to make it heap
allocated. But then I need a place to store the pointer, so that it can be freed
again, which would be unallocated storage too. :(
It's probably even better to just let the StandAlone...Scanner get a scanner
constant pointer as argument.
