The EngineBuilder shouldn't be trying to destroy the module. Looking
at EngineBuilder::create's control flow, the most plausible problem is
that the TargetMachine is null, so EngineBuilder::selectTarget has
gone wrong.

If so, maybe the Module's triple is wrong or your LLVM is compiled
strangely so no targets can be found? Either way, it's probably time
to pull out the debugger.
