both addr=0x4d6149 and addr=0x4d616f are not aligned on a 4-byte boundary like one would expect on armv7.

Is it possible the compiler is emitting an unaligned load and other OSes for the architecture are masking it? Seems like we might need to reproduce this in gdb to get anything useful out of it.
