+-- Issue:
+-- I'm not sure if my experimental code is allowed in VHDL, but it let GHDL
+-- crash. So I'm reporting just an unhandled exception.
+--
+-- GHDL's output is:
+-- .\attribute.vhdl:64:58: can't match 'image attribute with type character
+-- .\attribute.vhdl:64:53: (location of 'image attribute)
+-- finish_sem_name: cannot handle IIR_KIND_OVERLOAD_LIST (??:??:??)
