Bytecode file
With:
LLVM (<a href="http://llvm.org/">http://llvm.org/</a>):
LLVM version 3.4svn
DEBUG build.
Built Sep 14 2013 (21:22:42).
Default target: x86_64-unknown-linux-gnu
Host CPU: corei7-avx
clang version 3.4 (trunk 190758)
Target: x86_64-unknown-linux-gnu
Thread model: posix
Running the optimizer with instnamer and lowerswitch seg faults. This
particular seg fault error occurs in several (10+) files in the Linux Kernel
x86. I'm able to run llvm-dis on it for inspection. Here's the failure log
file. One of the .bc in question goes in attach.
