Hi all,
I've recently upgraded to Mac OS X 10.6.2 in order to run the Analyzer for
Xcode and it's pointing out some potential memory leaks that really have me
confused. A typical example is where I have a method that allocates and returns
something like a CGPDFDocumentRef or CGContextRef. The analyzer reports that
the object allocated and stored in the variable is potentially being leaked,
however, if I call the appropriate release, such as CGPDFDocumentRelease or
CGContextRelease in the calling method it's reported as an incorrect decrement
of an object not owned by the caller.
Is this just a limitation in the ability of the Analyzer to track the
allocation/freeing of an object or am I missing something fundamental.
Sample below:
- (id)callingMethod: {
CGPDFDocumentRef documentRef;
const char *buffer;
snip...
documentRef = [self getPDFDocumentRef:buffer];
snip...
CGPDFDocumentRelease(documentRef);
return xxxxx;
}
- (CGPDFDocumentRef)getPDFDocumentRef:(const char *)filename {
CGPDFDocumentRef document;
snip...
document = CGPDFDocumentCreateWithURL(url);
return document;
}
thanks,
Bob_______________________________________________
