The test displace-steps over a vfork syscall. In the special case of
displace-stepping over a (v)fork, GDB needs to adjust both the parent and the
child back from the displace stepping scratchpad. Since GDBserver doesn't
support following (v)forks yet, gdb is never informed about the child, and so
the child
ends up continuing freely, unadjusted, from the scratchpad, and crashes.
