Summary0002357: can't handle lemma with 3 labels
DescriptionRunning "frama-c -wp adjacent_difference_inv_cpp.cpp" on the attached program reports an error in line 6: "logic label `L' not found". The error message disappears when
(1) the file is renamed to "adjacent_difference_inv_cpp.c", and processed by plain Frama-C,
(2) the middle conjunct "foo{L}(1)" is removed in line 6, or
(3) label "M" is omitted in the header of "lem", and the rightmost conjunct is changed to "foo{L}(2)".
Consistently renaming the labels doesn't make the error message vanish.
TagsNo tags attached.

The the surrounding 'extern "C" { ... }' can be removed without affecting the above description. (However, I apparently don't have permission to do that.)

Issue lies directly in the C++ part of the plugin (ACSL++ parser): produced AST already lacks the L label.
