Hi all,

I have just noticed that an old version of tkcon (copied here:
http://www.ellogon.org/~petasis/tcl/tkcon_crash.tcl) crashes ActiveTcl
8.5.7. Can anybody verify this?

George

The latest build of 8.6 works fine though...

Crashes on my linux system with tcl8.5.7, too. Altough it is not 100%
tcl 8.5.7. It is somewhere in between 8.5.7 and 8.5.8.

Here is the backtrace

8.5.7
% package require Tk
8.5.7
% exit

ActiveTcl 8.5.7.1 I think you mean.

Due to the timing of its construction, it got released after
Tcl Bug 2884203 got committed but before it was fixed.

Since the fix is in the source code release of Tcl 8.5.8, the next
ActiveTcl should be ok as well.
