Extended Description
On the x86-64 JIT, calling a C function registered via ExecutionEngine::addGlobalMapping, produces a crash.
Inpecting the JIT'ed generated machine code shows that the call does not refer the address of the C function. It is like the global mapping for the function didn't exist.
Attached is a C++ test case that crashes on x86-64 and succeeds on x86.
