Assigned value is garbage or undefined in UIImage+StackBlur

Has anyone noticed following warnings while Analysing code? I have tried fixing by initialising values for rsum or dv but not able to resolve them. Has anyone fixed them?

...StackBlur/UIImage+StackBlur.m:155:4: Assigned value is garbage or undefined
...StackBlur/UIImage+StackBlur.m:244:4: Assigned value is garbage or undefined

Thanks.

Hi, to fix this just add an assert to tell the compiler that dvcount cannot be zero:
const size_t dvcount = 256 * divsum;
assert(dvcount>0);
int *dv = malloc(sizeof(int) * dvcount);

For 155:4 warning I found these answer http://stackoverflow.com/questions/16928381/cfmutabledataref-released-but-still-causing-a-memory-leak
I hope it helps.
