Summary0002348: unknown variable in contract is not treated as an error
DescriptionThe attached C/C++ code is treated differently by Frama-C and Frama-Clang The C file 'unknown_variable.c' is correctly rejected by Frama-C with wit the the message frama-c -wp -wp-rte unknown_variable.c [kernel] user error: stopping on file "unknown_variable.c" that has errors. Add '-kernel-msg-key pp' for preprocessing command. When processing this file as C++ code frama-c -wp -wp-rte unknown_variable.cpp Frama-Clang only emits a warning (by the kernel) and continues processing Parsing unknown_variable.cpp (external front-end) unknown_variable.cpp:6:18: unknown identifier 'c' Now output intermediate result In my opinion, the C++ contract should be rejected as well.
TagsNo tags attached.

If I'm not mistaken, Frama-Clang implements the old "continue-annot-error" behavior, but nevertheless the warning should have come from the plug-in, not the kernel.
