# Test unwind info for functions which have been split into two or more parts.
# In particular, check we return the correct set of unwind plans when querying
# addresses which are in the middle of discontinuous functions.

## NB: This minidump exists only as a receptacle for the object file built
## above. This is a workaround for the fact that "image show-unwind" does not
## work without a Process object.
