The answer is "Maybe" to all three questions.

The reporter is trying to rebuild all of Extras, looking for compiler
warnings. While compilers can be wrong (example: uninitialized variables
passed by reference; another example: code which is compiled but never
executed at run-time; another example: a missing catch-all rule in a
function which is never called with arguments outside its well-defined
domain), "array subscript out of range" can lead to memory corruption
(write-access beyond array boundary) or undefined behaviour (read-access
outside array range).

After verifying the compiler's warnings, such reports should be forwarded
to upstream developers and are worth fixing, if the code is executed.
