John:
As so often happens... when I ran gdb again and looked more closely at
my code with the subject line call, I found that the previously
encountered segmentation fault and bad_alloc error message did not come
from that call. It comes from subsequent code that tries to use the
Cairo::RefPtr<Cairo::Pixbuf> that is returned by the call. The call to
"create" itself only generates
(myprog:480): glibmm-CRITICAL **: Glib::Interface::Interface(const
Glib::Interface_Class&): assertion `gobject_ != 0' failed
(myprog:480): GLib-GObject-CRITICAL **: g_object_ref: assertion
`G_IS_OBJECT (object)' failed
(myprog:480): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed
I am still struggling to figure out how to get the debugger to step into
the glibmm library code.
