False positives for unused variable

I'm getting a slew of errors like this in the minizip libs.

1055:17 Value stored to 'err' is never read

http://bitbucket.org/urbanairship/storefront/src/5cd9eba47943/Airship/External/ZipFile-OC/minizip/zip.c#cl-1055

but the value is read on like 1064

http://bitbucket.org/urbanairship/storefront/src/5cd9eba47943/Airship/External/ZipFile-OC/minizip/zip.c#cl-1064

and in the while loop itself on line 1049

http://bitbucket.org/urbanairship/storefront/src/5cd9eba47943/Airship/External/ZipFile-OC/minizip/zip.c#cl-1049

Let me know if I should file a bug report and if there is any way I
can work around the errors for now.

Hi Steven,

The analyzer is correct. The value is overwritten on line 1060, prior to the read on line 1064. The warning is not that 'err' is never read, but that the value you stored to it is never read.

Same reason as above. The value gets overwritten on line 1060.

This doesn't look like a false positive.
