[Xotcl] Loading XOTcl crashes

[Kurt Stoll]

Thank you Gustaf.  I did open up a thread in their forum, but have not seen any responses yet.  It's at:

	http://community.activestate.com/node/8750

I'll see if I can find the error handling code that is being called to determine where the issue is.

We do not have Komodo here, which is a commercial product (most likely with a commercial support). Is the a public visible forum with your discussions, maybe i can get a clue from it... From the snippet below, there seems to be a problem with the error handling (where i see nothing special from the xotcl side).

All three environments (Komodo V7, V6, and Terminal / tclsh) are using the same version of Tcl (8.5) and the same version of XOTcl (1.6.6 - I know, down rev by one release).  All three versions point to the same library file: /System/Library/Tcl/8.5/xotcl1.6.6/libxotcl1.6.6.dylib.
