UnwindCursor<A, R>::getInfoFromEHABISection assumes the last entry in the index table never corresponds to a real function. Indeed, GNU ld always inserts an EXIDX_CANTUNWIND entry, containing the end of the .text section. However, the EHABI specification (http://infocenter.arm.com/help/topic/com.arm.doc.ihi0038b/IHI0038B_ehabi.pdf) does not seem to contain text that requires the presence of a sentinel entry. In that sense the libunwind implementation isn't compliant with the specification. This patch makes getInfoFromEHABISection examine the last entry in the index table if upper_bound returns the end iterator.
