sccinfo: fix generation of self-loop accepting runs
Reported by Juraj Major. * spot/twaalgos/sccinfo.cc (scc_info::get_accepting_run): Do not assume TRACK_STATES is enabled. * tests/core/autcross5.test: New file. * tests/Makefile.am: Add it. * NEWS: Mention the bug.

|
- In an automaton with acceptance condition containing some Fin, and
|
||||||
|
whose accepting cycle could be reduced to a self-loop in an
|
||||||
|
otherwise larger SCC, the generation of an accepting run could be
|
||||||
|
wrong. This could in turn cause segfaults or infinite loops while
|
||||||
|
running autcross or autfilt --stats=%w.
