The object is the emacs font cache. Specifically in this case (Debian,
X11, xft fonts, lucid widgets) it is
frame->output_data.x->display_info->name_list_element
where frame is a struct frame*, such as the first argument of
font_load_for_lface()
In the original message for this bug report I showed 'pp' output for
this first argument of font_load_for_lface(). This function is called 4
times during the creation of one frame. I want to know why the font
cache is cleared before the 3rd call. I tried to examine the code, and
to place breakpoints in places that could be performing this cache
clear, but none of those places look like the right ones. If a
watchpoint is possible, it would tell me where this is cleared, instead
of me having to guess.
