It appears that the index value of a for loop changes within a nested function. In some cases, nested functions can be called by callbacks or other function calls leading to the loop index changing. This kind of bug is exceptionally hard to find, so Code Analyzer signals this situation even though in many cases the usage is benign.

Change the name of the for loop index or the variable of the same name in the nested function. If you must keep them as is, add a comment indicating the need and suppress the message as described in Adjust Code Analyzer Message Indicators and Messages.
