Bug 18981 – SIGSEGV during backtrace when debug info is compressed

To reproduce: 1) sample D code: void main() { throw new Exception("asdf"); } 2) compile it with debug info 3) compress the debug info with objcopy a.out --compress-debug-sections=zlib 4) run it Expected: Stack trace, or at least not crashing Actual: SIGSEGV
