Now I understand why your build doesn't crash: you didn't specify
GLYPH_DEBUG.  I build with --enable-checking='yes,glyphs'.  The
function where Emacs hits the assertion is not compiled in without
GLYPH_DEBUG being defined.

Not sure what are you asking.  The Windows build seems indeed to be
devoid of XPM, but the Unix build does display color icons on the
toolbar.  Try using image-type-available-p to see which image types
are supported.
