As a consequence, Coq fails to compile the generated proof scripts for a null pointer check: > Error: The reference Memory.Mk_addr was not found in the current environment. ### Additional Information : Frama-c Argon 18.0 Coq 8.6 why3 0.88.3 ### Steps To Reproduce : cat <<EOF >id.c /*@ requires \valid(p); ensures *p == \old(*p); */ void id(int* p) { int tmp; if (p == (int*)0) return; tmp = *p; *p = ~~tmp; } EOF frama-c -wp -wp-rte -wp-split -wp-prover why3ide id.c # Select Postcondition Line 2 # Coq # Edit # Replay # => Error: The reference Memory.Mk_addr was not found in the current environment.
