If list->charset_list != NULL and list->charset_count == 0, the Xmalloc call in copy_string_list might return NULL (I don't know whether it supports a size of 0), causing copy_string_list and XCreateFontSet() to return NULL. This seems unlikely to be triggered only by the exact font pattern lists I identified though. Ben. -- Ben Hutchings If God had intended Man to program, we'd have been born with serial I/O ports.
