Test case causing pango to crash in pango_layout_get_cursor_position (976 bytes, text/plain)
2008-08-11 15:41 UTC, Øyvind Kolås (pippin) 		Details

Description Øyvind Kolås (pippin) 2008-08-11 15:40:09 UTC 
If a \r\n is present in a buffer passed to a PangoLayout pango will abort the process with an assert not reached for some positions in the buffer.

** Pango:ERROR:(/tmp/buildd/pango1.0-1.20.5/pango/pango-layout.c:2147):pango_layout_line_get_char_direction: code should not be reached
