Not unlikely. Sometimes your unwind involves cleaning up things that throw for the same reason as the original failure - e.g. failure to communicate with some piece of hardware. But you still try going through that unwind, right? Eventually you leave the context of accessing your hardware device entirely and are back to just working with system memory, the standard streams and some files, which would probably work fine. I have recently experienced this writing wrappers for the CUDA API for GPU programming.
