So the question is: why appending an array of only one element to an existing array causes memory problems?


It must copy the entire array.


Isn't it the same with snocU?

And, since the final result is the same, what happens to the temporary memory used for array copying?

I have executed the program with:
   +RTS -A128M -s -c -F1.1 -RTS

The memory seems to leak.
