N.B. I've found pdb files related to the GTK DLLs distributed as part of the hexchat gtk-win32 project (https://github.com/hexchat/gtk-win32).
Executing with these in place, the VS 2015 debugger is showing me that there is an intermittent issue when "pango_layout_clear_lines" is called. Ultimately a NULL pointer is passed to glib's "magazine_chain_prepare_fields" function. The issue can be recreated by creating and destroying a UI dialogue a specific number of times. Each text block in the UI dialogue is rendered by creating and destroying PangoLayout and PangoFontDescription objects. As this is an intermittent issue, and at a glib memory management level, I am not sure how to proceed. Any advice would be appreciated.
