Crashes when built for distribution

[GoogleCodeExporter]

What steps will reproduce the problem?
1. build for distribution (adHoc), install on device via iTunes
2. "run"
3.

What is the expected output? What do you see instead?
Works fine when built for debug, or built for distribution on the simulator but 
crashes to the 
springboard when built for adHoc on device

What version of the product are you using? On what operating system?
latest (0.9)

Please provide any additional information below.

The offending method is scanImageData, and within that commenting out 
parseExif: will cure 
the crash (but not return any data!) Typical crash log is below, this is a jpg 
imaged loaded into 
NSData and passed to scanImageData as follows:

NSData *uiJpeg =  [NSData dataWithContentsOfFile:[[NSBundle mainBundle] 
pathForResource:self.imageFilename ofType:@"jpg"]]; 
    if ([uiJpeg length] != 0) {
        [jpegScanner scanImageData:uiJpeg];

I am troubled by this problem a few days too. I think it is caused by memory 
use. When analysising big jpegs - 
more than 500KB - with methord scanImageData , it crashed.
I change methord scanImageData by myself and make it into steps:
    1. return exif data in the form of NSData*;
    2. release former jpegData to free memory;
    3. parse exif data with EXFMetadata parseExif method.
And then it works.

Hello ccairball,
Could you please upload the code of your scanImageData method to pastebin.com or
somewhere else? I am stumbling at this exact issue. Thanks.
