For gcc bug #10138 [1], gcc-11 gained a new way to show a
-Wmaybe-uninitialized warning. When an uninitialized array is passed by
`const T *` to a function, gcc-11 assumes the array is an input to the
function, and warns accordingly. This is often useful, but is incorrect
for the Rebirth partial_range code. In this code, the pointer is only
passed so that the eventual exception can print the memory address of
the affected array. The called function does not dereference the
pointer, and so cannot be influenced by any uninitialized values in the
underlying array.
Change the report function to take the array address in a `uintptr_t`,
and cast it back for printing. This silences the gcc-11 warning, while
preserving the previous semantics in the code.
