When recovering from a panic, restore the caller's frame pointer before returning control to the caller. Otherwise, if the function proceeds to run more deferred calls before returning, the deferred functions will get invalid frame pointers pointing to an address lower in the stack. This can cause frame pointer unwinding to crash, such as if an execution trace event is recorded during the deferred call on architectures which support frame pointer unwinding.
