<pre>This issue is about an IRC crash report about LLDB (r176306). It seems to be
happening during the initialization of the LLVM disassembler.
OS: Linux
Compiler: clang (176308)
Build system: cmake (release build)
Unable to reproduce locally with an older version of Clang (or GCC 4.6/4.7) but
the stack trace from the crash is:
(gdb) bt
