XtTextInvalidate has the following line in it:

ctx->text.lastPos = (*ctx->text.source->GetLasPos)(ctx->text.source);

In the procedures which create the source for ascii text widgets and
those which create the source for the text widgets the field
source->GetLastPos is never initialized.  As a result, calling
XtTextInvalidate causes a segmentation fault.

Am I suppose to provide a function for GetLastPos?  If so, Is
there a macro to call which will initialize the field with my
function?  

Perhaps I am missing something?

Thanks for your help.
