Carl,

The operative word is an API call to SetCurrentDirectory, which
accepts a single zstring paramter. For instance

z" c:\foo\bar\my\stuff" SetCurrentDirectory drop

Subject: Help about a (subtle) error ?

I'm working on a long program. Since several weeks, I noticed that from
time to time, the program crash just when exiting.

The error msg is always similar:

        "The instruction at '0x77aa446f' referenced memory at '0x0000030'.
        The memory could not be 'read'".

I have checked (as so as possible) the stack and memory usage near the exit
point: All seems to be OK...

....

Finally, I have today found a sure scenario to reproduce this crash:

With SF1.5 + Notepad or TextPad...

1. in the editor, open any SOURCE.F of THIS program, don't modify the text!
2. in SwiftForth, include the main source-file, execute main program word.
3. in the editor modify any text.
4. quit the program.

Scenari to ALWAYS crash on program exit:

        1 2 3 4
        2 1 4

But the following NEVER crash:

        1 2 4
        1 3 2 4

Is there one explanation, or is it an electro-static side-effect ?
