[Frama-c-discuss] Verifying recursive functions

Hello,

Frama-c reports a fatal error when I run it on the following code:


/*@
  requires n >= 0;
  ensures \result == \sum(0,n, \lambda integer i; i);
*/
int sum(int n) {
  if(n==0) return 0;
  else return n + sum(n-1);
}


This is the output:


~/progs/fc/sum> frama-c -jessie-analysis sum.c
Parsing

Fatal error: exception Assert_failure("src/jessie/interp.ml", 564, 19)


Is this a bug in Jessie?
