Description
Originally reported on Google Code with ID 376
```
CFI directives were removed in http://llvm.org/viewvc/llvm-project?view=revision&revision=192196
. Unfortunately incomplete unwind info may cause libgcc unwinder to segfault. This
indeed happens on my system when CHECK is triggered in internal_clone-ed process.
What about following Jakub's suggestion in https://gcc.gnu.org/ml/gcc/2013-11/msg00439.html
?
