It seems that the "CommandLine 2.0 Library" is using so much of static
everywhere cause the crash.

Did some experiments, and plugins without using the command line library works
just fine. Then had a little gdb session, where found that calling
'llvm::cl::ParseCommandLineOptions' method happens only once with -plugin
option, but with -add-plugin it happens twice. And it also have seen, that
plugins which are using the command line library are mutating the arguments for
the second call somehow, and this mutated call do the core dump.

Could not trace the root of the problem, but could work around and make the
command line library happy. If the parser is not member variable in the plugin
class, it works just fine.
