I am glad you were able to confirm what is very likely a memory management
problem.  You probably escaped the segfault for tkdemos.tcl by chance.

I noticed your later e-mail confirming they now work okay except for a
segfault at the end.

tk0[124] work fine for me without that segfault on exit, but I do get
that segfault for tk03.  I am sure this difference between us 
is just random chance when there are underlying memory management issues.

The motivation for all x??.tcl examples in the tk examples directory is so
that tkdemos.tcl will work.  The examples look much better under
tk/tkdemos.tcl then under tcl/tcldemos.tcl, but we want to test both.
However, tk/x??.tcl should be identical copies to tcl/x??.tcl so it sounds
like a build system screwup to me.  I will look into that.
