RENAME bla bla/ corrupts RAM:

[mattrust]

Describe the bug
An attempt to rename a directory on RAM: to its parent directory (e.g. RENAME bla bla/) causes corruption.

To Reproduce
Steps to reproduce the behavior:

1. Open a Shell
2. CD RAM:
3. MAKEDIR bla
4. RENAME bla bla/
5. DIR -> shows an empty directory
6. Press TAB for tab completion -> segfault

Expected behaviour
Show error message like "Invalid object name". That's what AmigaOS3 is doing.

[Kalamatee]

Is it the command at fault, or the DOS Rename function? Can you check under AmigaOS what the OS calls behaviour is?

[mattrust]

The AROS Rename command works under AmigaOS.

This issue was fixed in MorphOS 3.18 by the way.

[mattrust]

@polluks I had tested it in AROS after reading the MorphOS release notes ;-) Maybe I should try to contact the MorphOS developers.
