Description :
Output from "frama-c from03.c" is: from03.c:5:[kernel] user error: unexpected token '\from'
Output after reaminig to "from03.cpp": from03.cpp:5:23: Expecting ';' after assigns
However, according to the manual "ACSL Version 1.8 --- Implementation in Neon-20140301", fig.2.22, p.63, it is valid syntax.
I could image that such clauses can make sense, e.g. to specify that a function writes a certain variable to stdout; in security applications it may be undesirable to express such issues. (If I'm wrong here, the above error message wouldn't be an issue.)
