--- Comment #1 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Your program appears to have undefined behavior:

$ clang interleave_bits_true.c -fsanitize=undefined-trap
-fsanitize-undefined-trap-on-error
bin $ ./a.out
Illegal instruction: 4

The shift by "i+1" will be undefined when i is 31.
