Two issues in graphviz here: firstly when the cr is extracted from a job
in plugin/pango/gvrender_pango.c:cairogen_polygon(), it should be
checked to ensure that it is valid before being used; secondly, the
error state set with _cairo_set_error should be checked after the call
to cairo_set_dash()
plugin/pango/gvrender_pango.c:cairogen_set_penstyle(). There may also
be an issue with cairo (the API docs should be checked), in that when an
invalid pointer is passed to cairo.c:cairo_set_dash(), the SIGSEGV
should be trapped, and an appropriate error set with _cairo_set_error(),
rather than crashing. If this is not an issue in cairo, then graphviz
must trap any expected signals as well as checking the error return
code.
** Changed in: graphviz (Ubuntu)
Status: New => Confirmed
