The unwind destination does not have a landingpad instruction!

[Behroosh]

I am working with "bfs" from the suggested test programs. I managed to instrument it when the target register is the destination register (dstreg). However, I get the following error message (in the instrumentation phase) when having source registers (allsrcreg) as target registers.

The unwind destination does not have a landingpad instruction!

I also used the latest version of LLFI and still got the same error message.

Hey, I also have the same problem. Just want to ask did you fix up the problem yet?
