I am creating an ExecutionEngine using the LLVMCreateExecutionEngineForModule function from the C API. I am get a set fault with the following backtrace.

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000120

I have called LLVMLinkInJIT before this.

Can anyone help?

Hi Eric, if you build LLVM with assertions enabled (configure with
--enable-assertions) you may get a helpful error message.

Ciao, Duncan.
