+AT_SETUP([Static symbols with forward decls and -i^s])
+AT_KEYWORDS([static fdecl])
+
+# Up to version 1.1 static symbols with forward declarations caused
+# segmentation faults when used with -i^s.
+#
+# Synopsis: Normally static functions are not added to callee lists
+# of their callers in -i^s mode (see add_reference() and call() in parser.c),
+# therefore cflow 1.1 assumed it was safe to free them in static_processor().
+# However, there is an important exception: if the function storage type is
+# not known at the time of reference. Such functions are added to callee lists
+# and freeing them causes coredumps.
+#
+# To reproduce the case we need two source files: first with the actual test
+# program and the second, empty, one, whose purpose is to trigger additional
+# memory allocations after symbol deletion.
