Just in case it's not obvious, the fact that this address is unaligned
is the least of your worries.  Even if alignment didn't matter, you
would just get a segfault instead since 0x25 is never going to be a
valid pointer.

I guess you need to investigate where the value in r2 is coming from and
figure out why it has this bogus value.
