Comment 13 for bug 1853617

After analyzing exactly the testcase5 ..
with a standard call stack when printing to pdf:
geda-gaf/libgedacairo/edarenderer.c \
eda_renderer_draw
 eda_renderer_draw_text
  eda_renderer_prepare_text
   eda_renderer_get_font_descent
the calculated descent (metrics->descent) in line 864:
 metrics = pango_context_get_metrics (renderer->priv->pc, desc, NULL);
has improper value for the second string from testcase5.
I'm sure the function argument *desc is valid
and renderer->priv->pc looks good .. what is wrong?
