...problem. This is getting to I think CodeGen then crashing. I've found that the module itself needs to be non-trivial to cause the crash. Here is the module I'm testing with [3]. In case it is relevant: to get my pass to run during LTO I added "PM.add(createHelloPass())" to PassMangerBuilder::populateLTOPassManager. I'm using binutils-gold on Linux (Ubuntu 14.04 LTS).
