启用Guard Malloc时，UIImagePNGRepresentation中的EXC_BAD_ACCESS错误

Question

I am getting EXC_BAD_ACCESS error at UIImagePNGRepresentation() when Guard Malloc enabled and when I disable I am not getting any error while converting image. I have gone through google for solution but I am not find any working solution approach. below is the code.

UIImage  *image, *newImage;
NSData *imageData = [NSData dataWithContentsOfFile:@"somepath"];
            image = [UIImage imageWithData:imageData];
NSData* data = nil;
        data = UIImagePNGRepresentation(image);
        // write to temp directory and return URI
        NSString* docsPath = [NSTemporaryDirectory ()stringByStandardizingPath];
// more code

this is a part of phonegap plugin code and any suggestions are really helpful. Thanks.
