I would be very careful about that conclusion. Reading that thread it sounds like you’re relying on Claude to make this conclusion but you haven’t actually verified what the address being returned actually is.

The reason I’m skeptical is three fold. The first is that it’s generally impossible for a filesystem to mmap return a pointer that’s not page boundary aligned. The second is that unaligned accesses are still fine on modern ARM is not a SIGBUS. The third is that Claude’s reasoning that the pointer must be 8-byte aligned and that indicates a misaligned read is flawed - how do you know that SQLite isn’t doing a 2-byte read at that address?

If you really think it’s a bad alignment it should be trivial to reproduce - mmap the file explicitly and print the address or modify the SQLite source to print the mmap location it gets.
