[Bug 1027454] [NEW] misdisassembly/and seg of ARM on 32bit hosts

[Dave Gilbert]

Public bug reported:

This corresponds to binutils bug
http://sourceware.org/bugzilla/show_bug.cgi?id=13135

There are mismatched printf formats and arguments that cause segs or incorrect offsets in ARM disassembly in
binutils 2.22; the simplest example (on 32bit x86 Quantal) from the upstream bug is:


% perl -e 'print pack("V*", 0xed69cdcb)' >/tmp/bad.insn
% objdump -b binary -m arm -EL -D /tmp/bad.insn
