The "foo bar baz" example works fine in current SVN (r4893), it no longer gives a warning.  The segfault had gone already long ago.  So, considering this fixed.

Have tested this with both 2.1.9 (current unstable) from nano-editor.org and with svn trunk as of today (May 14th '09).

Steps to reproduce:

1.) Run nano without any arguments so it has a fresh buffer.
2.) Type 'foo bar baz' (minus quotes) on the first line.
3.) Place the cursor on the 'b' of 'bar' and set the mark with either ^6 or M-A.
4.) Move the cursor to the space beyond 'bar' as if to cut/copy 'bar' and copy using M-6.
5.) Paste using ^U one or more times (the first paste operation results in the message '[ Internal error: can't setup uncut.  Please save your work. ]' appearing on the status bar but it appears to uncut successfully).
6.) After pasting, undo with M-U.

This results in a segmentation fault.

There seems to still be some outstanding crash bugs with the undo/redo function.   Certain circumstances cause the editor to crash, more frequently when using an active syntax highlighting set.  This needs to be fixed before the next stable branch.
