I hope you now better understand why I didn't respond to Juanma's
report immediately.  There are too many layers at work here.

Which assertion?  The one in XFIXNUM?

I do hit it here.  Unless some sort of bug happens before.  For
example, when using (left . foo).

The X build sets 'left' only in 'gui_figure_window_size' whereafter it
immediately sanitizes it into f->left_pos which is later on used by
XCreateWindow.
