llvm dev - Jun 2013 - [LLVMdev] is this a bug of llvm::JIT::getPointerToBasicBlock?

I am reading the implementation of llvm::JIT::getPointerToBasicBlock and I
think there might be a bug in it.

'getPointerToBasicBlock' first calls 'getPointerToFunction' and
then try to
look up the map returned by 'getBasicBlockAddressMap(locked)' to get the
pointer of the BasicBlock.

 'getPointerToFunction' calls 'runJITOnFunctionUnlocked' which
in turn
calls 'jitTheFunction'. However, in 'jitTheFunction, there is a
statement
'getBasicBlockAddressMap(locked).clear()'.  After returning from
'getPointerToFunction', the map is empty. So, you will never get the
pointer of the BasicBlock.

Is this a bug? Or I should not call the function this way?
