DDMathParser gives memory leak

Question

I am using DDMathParser in my Xcode project. I have a memory leak and I can't resolve it.

Instruments gives me following leaked objects:
_DDNumberExpression
_DDFunctionExpression

Can anyone help me?

My code for using ddmathparser:

NSString *result = [NSString stringWithFormat:@"%@", [string numberByEvaluatingString]];

DDMathParser author here.

I sure hope this isn't a leak in my code, but if the reproduction case is as simple as you say it is, then it's sure possible. The static analyzer isn't showing me any problems with the code, but the static analyzer also isn't perfect.

Here's what I need to debug this:

1. What is string? It's obviously an NSString variable, but I need to know the contents
2. Are you doing anything else with DDMathParser, or is it just this one line?

Edit

From your other question, I saw that you were using the string @"1+2". When I run that code in Instruments, I get no leaks (both with ARC and without). So yeah, I'm going to need a lot more information.
