Local memory banking error

This is a compiler crash due to some bug in the compiler; such issues cannot be directly addressed by the programmer. I recommend using the latest version of Quartus (v19.1) if you have a compatible BSP to see if the issue still occurs. If it does, the issue should be passed on to Intel engineers (I guess the forum moderators can do that). Since the fix will likely take a while to be implemented, your only choice in the meantime is likely to modify your code line by line to see which line triggers the crash and then try to come up with an alternative implementation that produces the same kernel behavior without including that line so that the compiler crash is avoided.
