(resending with smaller attachement)
Segfault in EE->getPointerToFunction.
I think it's blown the stack, gdb reports a never ending backtrace (below).
I generate llvm assembly and parse/verify OK.
Attached is the assembly. It is the smallest example
generated that causes the segfault.
If this EE uses a recursive function (??), it seems an inherent limitation
in how big llvm functions can be.
