I’ve found those “obvious” checks to be useful to catch unexpected hardware issues as well. I had a customer upset that my code was crashing- I sent a debug version with asserts around some arithmetic core to the algorithm and lo and behold those asserts failed His machines memory was bad and corrupting the internal state of the application. Until I could prove that his machine was calculating the equivalent of 2+2=5, he wouldn’t believe us.
