[LLVMdev] LLVM segmentation fault / need use Instruction instead of Instruction*

[Alexandru Ionut Diaconescu]

getPrevNode<http://llvm.org/docs/doxygen/html/classllvm_1_1ilist__node.html#a77b897207ef0a1ae95c404695aed9a4b>()
 Get the previous node, or 0 for the list head. I don't see any method like
hasPrevNode.
It can be a weird problem because "current->getPrevNode()" is indicating to
"current" itself (the problem appears for the BB with only one element)?
