backtrace from crash in xcopy.exe

The builtin implemetnation of xcopy.exe has a bug wherein xcopy pagefaults on
exit when the source file does not exist, and option\e (copy empty
subdirectories) is used. Example below:

wine xcopy.exe /e Z:\home\robbak\testdir\nonexistant
z:\home\robbak\testdir\nonexist_target
Path not found

wine: Unhandled page fault on write access to 0x003a005e at address 0x7bc460f4
(thread 0042), starting debugger...
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr
0x7bc460f4
[1]+  Done                    wine notepad.exe

Attached is a dump created while running autopatcher, which runs uses
xcopy.exe. (my simple test did not produce a backtrace.)
