sample code
The naked function behavior change depending on '-g' flags.
When -g is given, the .cfi_startproc is setted, so i'm able to put unwind unfo.
If I remove the flag, there is no more "stratproc" directive and cause a clang
crash.
$ clang++36 -m32 -g -c check.cpp
$ clang++36 -m32 -c check.cpp
fatal error: error in backend: No open frame
clang: error: clang frontend command failed with exit code 70 (use -v to see
