Native shell on ReactOS breaks when non-existing command

ReactOS-bootcd-0.4.17-dev-1129-g05c8323-x86-gcc-lin-rel

When I enter a non-existent command, on ReactOS this native.exe program breaks; while on WinXP and WinServer2003 it shows message "not recognized" .

I manually entered it into the registry and copied native.exe to system32 (not used .reg scripts).

In nativeshell_0.12.rar is source.

when I try not-existing command, row:

(sdk/lib/rtl/heap.c:2323) HEAP: Trying to free an invalid address 0006F370!
(ntoskrnl/ke/i386/exp.c:1032) Kill native.exe, ExceptionCode: c0000005, ExceptionAddress: 7C94E410, BaseAddress: 01000000, P0: 0, P1: 55732

explains it!

Also, now I see that sysinternal's autoruns too can set "Boot execute" for native programs.
