[Xotcl] how to track a segmentation fault problem in Xotcl?

[Catherine Letondal]

Hi,

I have just re-installed Xotcl 1.0.2 version and succedeed in running my
application with some minor changes since the last xotcl version I used on this
platform (Sparc/Solaris 7) was the 0.9 :-)

I have a segmentation fault that occurs when a command is called from a Tk menu. 
The command is attached to the popup by a:
	add command -command 
statement on a menu Tk widget that is raised by a tk_popup.

However, the very same command, when called from the tcl (xowish) interpreter, works 
and does not produce any core dump. And most menu items also work well.

So my question is: how do I debug such a situation? 
Thanks for any help...
