#55 Abort trap 6: error on macOS Sierra (Tcl/Tk 8.6.6)

[sigzero]

I have installed the tcl-tk recipe from homebrew on macOS Sierra.

The brew recipe is here: https://github.com/Homebrew/homebrew-core/blob/master/Formula/tcl-tk.rb

I have setup my environment to point to this.

I have installed tklib separately.

I can run all the widget demos no issue.

I can "package require ctext" and no issues.
-> tclsh
% info patchlevel
8.6.6
% package require Tk
8.6.6
% package require ctext
3.3
% exit

When I try and start tkcon...I get:

-> tkcon
Abort trap: 6

This doesn't happen if I have installed Tcl/Tk via ActiveTcl.

This is due to Ruby/Tk core issues, not tkcon.
