Re: [Haskell-cafe] possible memory leak in uvector 0.1.0.3

Hi.

In the "help optimizing memory usage for a program" I discovered some interesting things:

2) UArr from uvector leaks memory. I'm rather sure about this.

Note it was just allocating more than was required, it wasn't "leaking" it in any sense (i.e. losing track of the memory).

Using this version memory usage is, finally, 643 MB! (and execution if a bit faster, too).

Yep, known bug, and closed last month.

The other program, with a lot of array concatenations, still eats a lot of memory...

Concatenating arrays generally copies data. Which uses memory.
