<div>
<pre>When accessing a SectionRef::getContents() StringRef, the initial pointer is
valid, and length is correct but the memory mapped at the pointer is not large
enough for the length supplied. It's possible that the data pointer is
misaligned. When accessing memory near the end of the section pointer it will
causes a invalid access and crash.
Attached is a sample binary that causes a crash, the invalid section in the
'.bss' in this case.
In order to reproduce: llvm-objdump -disassemble-all /path/to/attachment</pre>
