On MSVC 2008 I get a crash with while calling ExecutionEngine::addGlobalMapping
(as seen below), in 2.7, 2.8 and trunk.
It throws an unhandled exception (an access violation) seemingly at
MutexImpl::acquire().

Reduced test case:

void foo() { }
int main() {
  ExecutionEngine *jitengine =
EngineBuilder(jitmodule).setEngineKind(EngineKind::JIT).create();
  Function *func = Function::Create(TypeBuilder<void(),
false>::get(getGlobalContext()), GlobalValue::ExternalLinkage, "foo");
  jitengine->addGlobalMapping(func, (void*)foo);
}
