Hi @antmox, thanks for the heads up. I'm not at my desk right now (its after work hours here). Did you bisect the issue to this patch? This one adds some new behaviour but keeps it off by default. I can't check  right now but I suspect it's e419084da7a00b269368aeb95698e0d36b24e8ec that is causing the issue, which turns on the new behaviour by default.

If you've got the bandwidth, please can you revert e419084da7a00b269368aeb95698e0d36b24e8ec  (or try adding the `-mllvm` option `write-experimental-debuginfo-iterators-to-bitcode=false` to those tests). Otherwise I will be able to come back and do it in an hour or so.
