Subject: psppire-output-view.c: added check for view->xr - fixes bug #45421
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5c6e86d036ccb49f6487f8a10cb4586cb4fc4c23;p=pspp

psppire-output-view.c: added check for view->xr - fixes bug #45421

The output windows crashed when an empty syntax window is executed. The
rerender function got called without a valid view->xr (=NULL). I added a
check for this condition and create a new view->xr as it is done in the
psppire_output_view_put function.

This fixes bug #45421: Crash when trying to run empty syntax
