All these warnings are false positives. The variables are initialized by prior calls to the nodeAcquire() function. The problem is that nodeAcquire() does not necessarily initialize the variables, but if it does not, it returns a result code other than SQLITE_OK, and in those cases, the code that uses the variables that nodeAcquire() was suppose to have initialized is never reached. Thus there is no possibility of using an uninitialized variable. However, the code in question is not on a critical path. Hence, I have now added extra (unnecessary) local variable initializations in the relevant RTree indexing routines so that these warnings should now be suppressed. -- D.
