Description :

access to a structure field in a lemna does not seem to work

typedef struct { int i; } T;

/@ lemma toto{L}: @ \forall T t; t.i == 0; @/

Additional Information :

frama-c -jessie -jessie-atp alt-ergo unused.c [kernel] preprocessing with "gcc -C -E -I. -dD unused.c" [jessie] Starting Jessie translation unused.c:4:[jessie] failure: cannot handle this lvalue [jessie] warning: Unsupported feature(s). Jessie plugin can not be used on your code.

rem : as soon as t is actually declared (of type T) prior to the lemna and an explicit access to t.i is done, this works
