I could boil down the example causing the "Uncaught" message to the following: /*@ axiomatic a1 { logic boolean isList{L}(int *b, integer f); logic integer jLgth{L}(int *b); axiom a2{L}: \forall int *b; isList(b,b[5]); axiom a3{L}: \forall int *b; jLgth(b) == 0; } */

This thread on frama-c-discuss suggests that the issue lies in the two functions/predicates declared in the axiomatic block. A workaround until this is fixed would be to declare separately isList and jLgth (putting the axioms in the latter). Note that it might imply to write some reads clauses for isList (while they'd be inferred from the axioms in the case of only one axiomatic).

I'm fine with the work-around Virgile suggested in his above note 728. As far as I'm concerned, the issue may be closed.
