It looks like the ARM sections are violating the assumption in find_section
that the sections are non-overlapping regions of memory. This causes the binary
search to end up in the wrong section:

in find_section():

find_section should find the .text section. However that overlaps .rodata,
.bss, .data, and .note.gnu.build-id sections.  As result the converges to
sections 3 or 4 which do not contain the addr.
